Subject [jira] [Commented] (HDFS-11732) Backport HDFS-8498 to branch-2.7: Blocks can be committed with wrong size
Date Tue, 02 May 2017 00:10:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11732?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15991855#comment-15991855
] 

Zhe Zhang commented on HDFS-11732:
----------------------------------

I tested all unit test failures in the HDFS-8498 [report|https://issues.apache.org/jira/browse/HDFS-8498?focusedCommentId=15987985&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15987985].
The only one reproducible locally is:

{code}
java.io.IOException: Failed to save in any storage directories while saving namespace.

	at org.apache.hadoop.hdfs.server.namenode.TestFSImage.testCompression(TestFSImage.java:68)
{code}

I suspect it's an issue with branch-2.7. Will verify soon.
