-----------------------------------
Hi Steve W,
I do not want to raise the bar to code contributions. I'm grateful that people
manage to find time to file a JIRA and post a patch in the first place.
Requiring another couple hours and patch revs might be the difference between
getting something committed vs. having the person get discouraged and
disappear. I see this happen all the time as it is.
Let me also step through why I think follow-ons are good:
* It's easy for interested parties to track. The JIRA summary will almost
certainly say "update filesystem contact", and we could also have a JIRA label
like "fscontract" or "hcfs" which people can watch.
* The follow-on JIRA will focus solely on the contract, so it should be easier
to review.
* I don't know if your average committer is able to properly review spec
changes anyway. Most of us do not maintain a HCFS, so do not necessarily have
the same understanding of the concerns as someone who does. Getting a
rubberstamp +1 to the spec change isn't that meaningful.
I'd appreciate if we could take any further discussion to common-dev /
hdfs-dev, as this JIRA is not the right forum.

> 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
