Detailed Description
Referring to fig. 1, in a first aspect, an embodiment of the present application provides a data processing method for a zookeeper client, including the following steps:
step 101: and acquiring the IP address of the server in the zookeeper cluster and the corresponding port information which are input by the user.
Zookeeper is a formal sub-project of Hadoop, is a reliable coordination system for large-scale distributed systems, and provides functions including: configuration maintenance, name service, distributed synchronization, group service, etc. The Zookeeper aims to package complex and error-prone key services and provide a simple and easy-to-use interface and a system with high performance and stable functions for users.
Zookeeper clusters typically consist of more than three servers. When a zookeeper cluster is deployed, a user can input configuration information of the zookeeper cluster through an Application Programming Interface (API), browse configuration requests generated according to the configuration information and send the configuration requests to a central control server, the central control server receives the configuration requests and generates basic configurations of zookeeper instances of the zookeeper cluster deployed on a belt, and therefore the zookeeper instances are generated and sent to each server to be deployed, each server finishes deployment of the zookeeper instances on the local server and starts the deployed zookeeper instances, and therefore the zookeeper cluster is formed.
Step 102: and generating a node tree corresponding to the server information according to the IP address and the corresponding port information.
Step 103: and acquiring all target nodes of the node tree and corresponding data processing requests, wherein the target nodes are nodes selected by a user on the node tree, and the data processing requests are one of target node deletion requests, requests for creating child nodes under the target nodes, requests for modifying, adding and deleting node data of the target nodes and requests for importing or exporting the node data of the target node data.
The target nodes can be selected by the user on the node tree according to actual requirements, and one or more target nodes can be selected. The zookeeper client provided by the embodiment of the application can realize the creation or deletion of the node, the modification, addition or deletion of the node data, and the import and export of the node data, thereby perfecting the functions of the existing zookeeper and increasing the use flexibility.
Step 104: and if the data processing request is one of a target node deleting request, a request for creating a child node under the target node and a modifying, adding and deleting request of the node data of the target node, carrying out corresponding processing on the corresponding target node and/or the node data of the target node.
Step 105: and if the data processing request is an import or export request of the node data of the target node, importing or exporting the node data of the target node.
According to the technical scheme, the data processing method of the zookeeper client is provided, a user can select a specific node in a node tree to import and export node data, backup and restoration of the node data can be realized through the import and export of the node data, and the actual requirements of the user can be well met.
Referring to fig. 2, in another embodiment provided by the present application, the step 102 of the above embodiment includes the following steps:
step 201: and finding the corresponding root node in the zookeeper according to the IP address and the corresponding port information.
In zookeeper, a node is a node similar to the unix file system path, and data can be stored to or retrieved from the node. If flag is set to EPHEMERAL when a node is created, the node will not be in the presence of zookeeper when the created node and zookeeper lose connectivity. Each node has corresponding authority for different servers, specifically, matching with the access authority set by the node through the IP addresses and corresponding port information of different servers, and if matching is successful, indicating that the server can access the node to acquire the node data of the node. In this step, the IP address of any server in the zookeeper cluster and the corresponding port information, which are entered by the user, are used to find the corresponding root node, which is used as the root node of the node tree.
Step 202: and searching by using a recursive method from the root node until leaf nodes without child nodes are searched, and obtaining the node tree.
The specific implementation mode of searching by using the recursive method is as follows: searching from the root node to the downstream, finding whether the root node has a child node, if so, continuing to search whether the child node belonging to the root node has a child node, and so on until a node without child nodes, that is, a leaf node, is searched, obtaining a node tree consisting of the root node, the leaf node, and a plurality of intermediate nodes, specifically referring to the node tree shown in fig. 5, where node a is the root node, node D, E, F, G is the leaf node, and the rest are the intermediate nodes. Preferably, the generated node tree can be presented to the user by a tree structure, so that the user can intuitively know the node relation related to the server of the query.
Referring to fig. 3, in another embodiment provided by the present application, when the data processing request is a node data request for deriving the target node, the step 105 includes the following steps:
step 301: traversing from each of the target nodes to a leaf node without child nodes.

Step 302: node data stored from each of the target nodes to all of the leaf nodes having no child nodes is obtained.
The node data includes data related to the node, such as node configuration data and the like.
Step 303: all of the node data is derived.
Step 304: and storing all nodes from each target node to leaf nodes without child nodes and all derived node data into a preset file.
All nodes and the exported node data are stored in a preset file, and the data can be backed up to prevent the node data from being restored when the data is lost or tampered.
Referring to fig. 4, when the data processing request is a node data request for importing the target node, the step 105 includes:
step 401: and acquiring a target file, wherein the target file comprises a first node directory of each target node and corresponding target node data.
The target file is a file to be imported into a designated node by a user, and the file format of the file must be the same as the file format stored by the node of the zookeeper client provided by the application. The target file may include node directories corresponding to all target nodes and corresponding target node data. If the user sets all the nodes on the node tree as target nodes, the node data of all the nodes needs to be imported, namely, the node data is imported in a full amount.
Step 402: judging whether each target node stores a second node directory which is the same as the first node directory of the target node, and executing a step 403 if the target node stores a second node directory which is the same as the first node directory of the target node; if the target node does not store a second nodal directory that is the same as the first nodal directory of the target node, then step 404 is performed.
Step 403: and importing the target node data corresponding to the first node directory in the target file into the second node directory.
Step 404: and creating a second node directory which is the same as the first node directory of the target node, and importing the target node data corresponding to the first node directory in the target file into the second node directory.
According to the technical scheme, a user can select one or more target nodes on the node tree according to actual requirements, corresponding target node data is imported, restoration of the node data is achieved under the condition that the data is damaged or lost, and data reliability and safety of the zookeeper client are improved.
