--------------------------------
Hi andrew and charles:
- For this JIRA, we all (1) certainly agree that an update to the unit tests
should be a part of this patch. And (2) A great place for such a test would
be {{hadoop-common/src/test/java/org/apache/hadoop/fs/contract}} . So, for
now, can we agree to that?
- Meanwhile, I can start the mailing list thread about this subject.
Thanks alot [~andrew.wang] for being clear and transparent about your position.
Looking forward to hearing from the overall community on this (imo) **very
important** topic.

> FileStatus should have a 'boolean isEncrypted()' method. (it was in the
> context of discussing with AndreW about FileStatus being a Writable).
> Having this method would allow MR JobSubmitter do the following:
> -----
> BOOLEAN intermediateEncryption = false
> IF jobconf.contains("mr.intermidate.encryption") THEN
> intermediateEncryption = jobConf.getBoolean("mr.intermidate.encryption")
> ELSE
> IF (I/O)Format INSTANCEOF File(I/O)Format THEN
> intermediateEncryption = ANY File(I/O)Format HAS a Path with status
> isEncrypted()==TRUE
> FI
> jobConf.setBoolean("mr.intermidate.encryption", intermediateEncryption)
> FI
