Bharath Mundlapudi commented on HDFS-2092:
------------------------------------------
Todd, Thanks for the reasons.
When we mean a client it can be anything, like TT/JT which has TIP/JIP. You are
right, client TIP/JIP can have references to JobConf. But then reference scope
is decided by client. And yes, eventually, we need to fix the FS cache you are
referring also if there are any leaks.

> At present, DFSClient stores reference to configuration object. Since, these
> configuration objects are pretty big at times can blot the processes which
> has multiple DFSClient objects like in TaskTracker. This is an attempt to
> remove the reference of conf object in DFSClient.
> This patch creates a light inner conf class and copies the required keys from
> the Configuration object.
