Tsz Wo Nicholas Sze commented on HADOOP-10425:
----------------------------------------------
Without the patch, the new test will failed since getContentSummary will count
also the CRC files created by ChecksumFileSystem.
> Incompatible behavior of LocalFileSystem:getContentSummary

> URL: https://issues.apache.org/jira/browse/HADOOP-10425
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs
> Affects Versions: 2.3.0
> Reporter: Brandon Li
> Assignee: Tsz Wo Nicholas Sze

> Unlike in Hadoop1, FilterFileSystem overrides getContentSummary, which causes
> content summary to be called on rawLocalFileSystem in Local mode.
> This impacts the computations of Stats in Hive with getting back FileSizes
> that include the size of the crc files.
