[jira] [Updated] (HADOOP-9230) TestUniformSizeInputFormat fails intermittently

["Karthik Kambatla (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HADOOP-9230?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Karthik Kambatla updated HADOOP-9230:
-------------------------------------

    Attachment: hadoop-9230.patch

I put more thought into this, but couldn't figure out the need for check against legacy splits that is failing.

Could change the legacySplits implementation, but then the test doesn't really make any sense.

Not finding an alternative, removed the check against legacy splits - uploading the corresponding patch.
