Subject [jira] [Commented] (ACCUMULO-4328) Run multiple tablet servers on a single host
Date Fri, 03 Jun 2016 20:17:59 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-4328?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15314726#comment-15314726

Dave Marion commented on ACCUMULO-4328:
---------------------------------------

bq. This looks like it would have a huge impact on users.

By default, it does nothing different than what happens today in 1.6 except for the pid in
the log (which could be undone in the logger properties)

bq. How do we track multiple processes in the shell scripts?

I backported the pid support, so each tserver instance is named 'tserver-N' and it has an
associated pid file.

bq. How do we differentiate multiple tservers on a host internally (inside the master)?

By hostname and port, just like today

bq. What configuration do users need to make to take advantage of this?

Take a look at the commented example in accumulo-env.sh, and they would need to set the tserver
client port to zero.
