--------------------------------------
Summary: Backport HDFS-11755 into branch-2.7 to fix a regression
in HDFS-11755
Key: HDFS-12641
URL: https://issues.apache.org/jira/browse/HDFS-12641
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.7.4
Reporter: Wei-Chiu Chuang
Assignee: Wei-Chiu Chuang
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.
