Subject [jira] [Commented] (HBASE-4746) Use a random ZK client port in unit tests so we can run them in parallel
Date Fri, 11 Nov 2011 23:40:53 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4746?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13148845#comment-13148845

Phabricator commented on HBASE-4746:

mbautin has abandoned the revision "[jira] [HBASE-4746] Use a random ZK client port in unit
tests so we can run them in parallel".

  This was committed into trunk (thanks Ted), abandoning this diff.  A reminder to committers
(quoting Nicolas) so that we don't have to abandon good revisions in the future:

  > since we've decided to allow more Metadata in our commit logs, it would be nice to
use the patch comments when committing this diff. Namely, including 'Differential Revision:
#' will allow Phabricator to automatically mark the review as closed.

> The hard-coded ZK client port has long been a problem for running HBase test suite in
parallel. The mini ZK cluster should run on a random free port, and that port should be passed
to all parts of the unit tests that need to talk to the mini cluster. In fact, randomizing
the port exposes a lot of places in the code where a new configuration is instantiated, and
as a result the client tries to talk to the default ZK client port and times out.
> The initial fix is for 0.89-fb, where it already allows to run unit tests in parallel
in 10 minutes. A fix for the trunk will follow.
