[jira] [Commented] (MAPREDUCE-6165) [JDK8]
TestCombineFileInputFormat failed on JDK8
[ https://issues.apache.org/jira/browse/MAPREDUCE-6165?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14229944#comment-14229944 ]
Akira AJISAKA commented on MAPREDUCE-6165:
------------------------------------------
The test unintentionally relies the iteration order of {{HashMap.entrySet()}}. Therefore the test fails in JDK8. {{MAPREDUCE-6165-reproduce.patch}} can reproduce the failure on JDK7.
