Andrew Wang commented on HDFS-6843:
-----------------------------------
Steve, are we now requiring all API changes to also update the spec? I'm fine
with filing a follow-on JIRA for this type of thing, but requiring it seems
kind of onerous and also counter to past precedent.
> Create FSDataInputStream & FSDataOutputStream isEncrypted() method

> 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
