      Description

      Our internal testing caught a regression in HDFS-11445 when we cherry picked the commit into CDH. Basically, it produces bogus missing file warnings. Further analysis revealed that the regression is actually fixed by HDFS-11755.

      Because of the order commits are merged in branch-2.8 ~ trunk (HDFS-11755 was committed before HDFS-11445), the regression was never actually surfaced for Hadoop 2.8/3.0.0-(alpha/beta) users. Since branch-2.7 has HDFS-11445 but no HDFS-11755, I suspect the regression is more visible for Hadoop 2.7.4.

      I am filing this jira to raise more awareness, than simply backporting HDFS-11755 into branch-2.7.
