Subject [jira] [Commented] (HDFS-12699) TestMountTable fails with Java 7
Date Tue, 24 Oct 2017 16:56:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12699?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16217252#comment-16217252

Íñigo Goiri commented on HDFS-12699:
------------------------------------

The failed unit tests is not related.
branch-2 didn't build but as [~aw] mentioned, it seems like the HDFS unit tests for branch-2
are taking too much memory and Jenkins is not able to run them.
I'd say we can commit this fix to both trunk and branch-2.

> Some of the issues for HDFS-12620 were related to Java 7.
> In particular, we relied on the {{HashMap}} order (which is wrong).
> This worked by chance with Java 8 (trunk) but not in with Java 7 (branch-2).
