Subject [jira] [Commented] (HDFS-14681) TestDisableRouterQuota failed because port 8888 was occupied
Date Tue, 30 Jul 2019 18:38:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-14681?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16896396#comment-16896396

Ayush Saxena commented on HDFS-14681:
-------------------------------------

8888 is Router Rpc Default port. Any idea what stayed up on 8888, is it problem with the UT
that blocks the port?
Well that is configurable, but still would be great to know how the port got occupied, its
better we solve the problem of port getting occupied

> It appears the test always occupy port 8888 and if I happen to have something using that
port already, the test fails.
