I am getting following error while listing table from hbase shell. Below is error list-

[root@data1 hbase]# hbase shell SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [jar:file:/usr/hdp/2.4.0.0-169/hadoop/lib/slf4j-log4j12-1.7.10.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/usr/hdp/2.4.0.0-169/zookeeper/lib/slf4j-log4j12-1.6.1.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

Please let me know how to fix this?

@Raja Ray In the future, please use the attachments feature instead of pasting raw logs. They're not easily readable with the WYSIWYG rendering.

Your master2 node doesn't seem to have any errors, which means it may just be slow to start. You can try taking a thread dump of the master while it's in this initialization state to see what it is stuck doing (jstack, HBase web UI, or `kill -3 <pid>`). There are no obvious errors in the logs (as you can also see) as to why the process has not yet fully started.

Hi @Raja Ray

We are also getting the same issue when I try to fix the hbase issue using -fix .

we are getting error "ERROR: java.io.IOException: Table Namespace Manager not ready yet, try again later" while creating a hbase table

I am also getting the same issue and restarted zookeeper and then region server and then hbase master but issue didn't resolve.

Even I have deleted hbase znode but still issue is there.
