Akira Ajisaka commented on HDFS-11180: -------------------------------------- Ran all the HDFS tests and the following tests failed. * TestJMXGet: HDFS-9072 (fixed in 2.7.3+ but not fixed in branch-2.6) * TestLazyPersistFiles: HDFS-9743 (fixed in 2.7.3+ but not fixed in branch-2.6) All other tests passed, so I'll commit this. > Intermittent deadlock in NameNode when failover happens. > -------------------------------------------------------- > > Key: HDFS-11180 > URL: https://issues.apache.org/jira/browse/HDFS-11180 > Project: Hadoop HDFS > Issue Type: Bug > Components: namenode > Affects Versions: 2.6.0 > Reporter: Abhishek Modi > Assignee: Akira Ajisaka > Priority: Blocker > Labels: high-availability > Fix For: 2.8.0, 2.7.4, 3.0.0-alpha2, 2.6.6 > > Attachments: HDFS-11180-branch-2.01.patch, > HDFS-11180-branch-2.6.01.patch, HDFS-11180-branch-2.7.01.patch, > HDFS-11180-branch-2.8.01.patch, HDFS-11180.00.patch, HDFS-11180.01.patch, > HDFS-11180.02.patch, HDFS-11180.03.patch, HDFS-11180.04.patch, jstack.log > > > It is happening due to metrics getting updated at the same time when failover > is happening.
