Hello,
My region servers die at regular intervals for unknown reasons.
I restarted HBase and region servers continued to die.
I solved it by eliminating Old WAL.
Now I'm going through the logs and trying to find the cause.
But I do not know where to look.
Please let me know if I need to watch
HBase and HDFS. Tail and post HBase logs from

My hbase java client works well.
Thanks alot for your comment, It is helpful for debug.
I have a suggestion. If hbase show raw exception (not wrap), it is more helpful

Gotcha. Unfortunately, we don't guarantee compatibility between that client
and the HBase server you're running, so the only way to solve the issue
will probably be to upgrade your client dependencies.
