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.

>                 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]

> 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.
