ClusterId read in ZooKeeper is null 处理

Posted 2020-11-23 shareforever-999

ClusterId read in ZooKeeper is null.

Re-running the program after fixing issue 1 will result in the following error in the log file (Oddly logged at INFO level)

 

 

现象1： baseZNode = /hbase

现象2：ClusterId read in ZooKeeper is nul

 

 检查Nodes

• ./zkCli.sh -server node01:2181,node02:2181,node03:2181
• ls /

 

 

 

解决办法

The HBase clients will discover the running HBase cluster using the following two properties:

1. hbase.zookeeper.quorum: is used to connect to the zookeeper cluster
2. zookeeper.znode.parent. tells which znode keeps the data (and address for HMaster) for the cluster

The value of zookeeper.znode.parent in hbase-1.2.0-cdh5.14.2/conf/hbase-site.xml is specified as /HBase (see below) which is correct but for some reason (still trying to figure this out), the value being printed is /hbase (现象1).

 

 

 So currently I’ve overridden this programatically in the client program by adding the following line to the program

conf.set(“zookeeper.znode.parent”, “/HBase”);
