Koji Noguchi commented on HADOOP-6202:
--------------------------------------
Probably this is happening because
HarFileSystem.makeQualified uses URI.toString() which escapes '%' to '%25'.
So string matching fails (as well as incorrect hash value).
> harchive: Har doesn't work on files having '%' character
