Subject [jira] [Commented] (HBASE-4209) The HBase hbase-daemon.sh SIGKILLs master when stopping it
Date Tue, 16 Aug 2011 21:49:27 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4209?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13086004#comment-13086004

stack commented on HBASE-4209:
------------------------------

I do not not remember why it SIGKILLs (I was going to blame hadoop saying we copied all from
there but I just checked and don't see it there so it must be an addition of ours). If plain
kill works for you, make a patch and we'll add it.  Thanks Roman.

> There's a bit of code in hbase-daemon.sh that makes HBase master being SIGKILLed when
stopping it rather than trying SIGTERM (like it does for other daemons). When HBase is executed
in a standalone mode (and the only daemon you need to run is master) that causes newly created
tables to go missing as unflushed data is thrown out. If there was not a good reason to kill
master with SIGKILL perhaps we can take that special case out and rely on SIGTERM.
