This exception is thrown by Apache ZooKeeper when it is unable to find the specified node in the ZooKeeper tree. In this case, it is trying to find the node "/hadoop-ha/mycluster/ActiveStandbyElectorLock" but it does not exist.
This error can occur due to a few reasons such as:
1. The node was never created in the first place.
2. The node was deleted by some other process or user.
3. There is a typo in the path of the node.
To resolve this error, you can try the following:
1. Make sure the node exists before trying to access it.
2. Check if there are any typos in the path of the node.
3. Ensure that the process trying to access the node has proper permissions to access it.

Caused by: org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /hbase/hbaseid
这个错误通常是由于 HBase 的配置问题造成的。在 HBase 中,每个 RegionServer 都有一个唯一的 ID,称为 HBaseID。这个 ID 通常存储在 ZooKeeper 中。如果 ZooKeeper 中没有找到这个节点,就会出现这个错误。可能的原因是 HBase 的配置文件中指定了错误的 ZooKeeper 地址,或者 ZooKeeper 中的节点已经被删除。你可以检查 HBase 的配置文件和 ZooKeeper 的状态来解决这个问题。
