Eli Collins commented on HDFS-2092:
-----------------------------------
Does this change mean that a Configuration object can now bee free'd because
there's one fewer ref to it? Otherwise it seems like we're now allocating a
DFSClient#conf in addition to a Configuration object which increases over all
memory usage no?
> Remove configuration object reference in DFSClient

> 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.
