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 ________________________________ From: jeff saremi <[email protected]> Sent: Wednesday, May 24, 2017 9:04:11 AM To: [email protected] 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
