ERROR: KeeperErrorCode = ConnectionLoss for /hbase/master

As an AI language model, I am not able to determine the exact cause of the error without more context. However, this error message indicates that there is a connection loss issue between the client and the HBase master server. This could be due to network connectivity issues, server overload, or other factors.

To resolve this issue, you can try the following steps:

1. Check your network connectivity and ensure that the client is able to connect to the HBase master server.
2. Verify that the HBase master server is running and is not overloaded.
3. Restart the HBase master server and try again.
4. If the issue persists, check the logs for more details about the error and consult the HBase documentation or community forums for further assistance.
