Colin Patrick McCabe commented on HDFS-5430:
--------------------------------------------
Looks good. +1 pending jenkins (and manual testing of TestOEV, since patch
won't pick up the binary change as we know)
> Support TTL on CacheBasedPathDirectives

> It would be nice if CacheBasedPathDirectives would support an expiration
