[jira] [Commented] (HDFS-2775) HA: TestStandbyCheckpoints.testBothNodesInStandbyState fails intermittently

["Todd Lipcon (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HDFS-2775?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13183502#comment-13183502 ] 

Todd Lipcon commented on HDFS-2775:
-----------------------------------

Yes, this just a test race. The issue is that the checkpoint is saved to storage, and only after that is {{mostRecentCheckpointTxId}} updated. So, the test sees the checkpoint and then the assert fails. We should probably fix this with some simple synchronization - but it's only a test problem and not a code issue.

> This test is failing periodically on this assertion:

>     assertEquals(12, nn0.getNamesystem().getFSImage().getStorage()

> {code}
> My guess is it's a test race. Investigating...
