Guangxu Cheng commented on HBASE-18131: --------------------------------------- Hi [~carp84], Did you still work on this? If not, do you mind if I work on this ? I got a patch for this on the works. > Add an hbase shell command to clear deadserver list in ServerManager > -------------------------------------------------------------------- > > Key: HBASE-18131 > URL: https://issues.apache.org/jira/browse/HBASE-18131 > Project: HBase > Issue Type: New Feature > Components: Operability > Reporter: Yu Li > Assignee: Yu Li > Fix For: 2.0.0, 1.4.0 > > > Currently if a regionserver is aborted due to fatal error or stopped by > operator on purpose, it will be added into {{ServerManager#deadservers}} list > and shown as "Dead Servers" in the master UI. This is a valid warn for > operators to notice the self-aborted servers and give a sanity check to > avoid further issues. However, after necessary checks, even if operator is > sure that the node is decommissioned (such as for repair), there's no way to > clear the dead server list except restarting master. See more details in > [this > discussion|http://mail-archives.apache.org/mod_mbox/hbase-user/201705.mbox/%3CCAM7-19%2BD4MLu2b1R94%2BtWQDspjfny2sCy4Qit8JtCgjvTOZzzg%40mail.gmail.com%3E] > in mail list > Here we propose to add a hbase shell command to allow clearing dead server > list in {{ServerManager}} for advanced users, and the command should be > executed with caution. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
