---------------------------------
Summary: Fix flakiness in TestQuorumJournalManager
Key: HDFS-4643
URL: https://issues.apache.org/jira/browse/HDFS-4643
Project: Hadoop HDFS
Issue Type: Bug
Components: qjm, test
Affects Versions: 2.0.3-alpha, 3.0.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Trivial
TestQuorumJournalManager can occasionally fail if two consecutive test cases
pick the same port number for the JournalNodes. In this case, sometimes an IPC
client can be cached from a previous test case, and then fail when it tries to
make an IPC over that cached connection to the now-broken connection. We need
to more carefully call close() on all the QJMs to prevent this.
