Potential deadlock in TestOverReplicatedBlocks
----------------------------------------------
Key: HDFS-863
URL: https://issues.apache.org/jira/browse/HDFS-863
Project: Hadoop HDFS
Issue Type: Bug
Components: test
Reporter: Todd Lipcon
Fix For: 0.22.0
Attachments: cycle.png
TestOverReplicatedBlocks.testProcesOverReplicateBlock synchronizes on
namesystem.heartbeats without synchronizing on namesystem first. Other places
in the code synchronize namesystem, then heartbeats. It's probably unlikely to
occur in this test case, but it's a simple fix.
