Subject Re: What is Dead Region Servers and how to clear them up?
Date Wed, 24 May 2017 19:10:38 GMT
these are the things I have done so far:


- restarting master (few times)

- running hbck (many times; this tool does not seem to be doing anything at all)

- checking the list of region servers in ZK (none of the dead ones are listed here)

- checking the WALs under <hbase_hdfs>/WALs. Out of 11 dead ones only 3 are listed here
with "-splitting" at the end of their names and they contain one single file like: 1493846660401..meta.1493922323600.meta

Subject: What is Dead Region Servers and how to clear them up?

Apparently having dead region servers is so common that a section of the master console is
dedicated to that?
How can we clean this up (preferably in an automated fashion)? Why isn't this being done by
HBase automatically?


thanks
