Refactor ClientProtocol.getSystemDir usage on the job client side to instead
use ClientProtocol.getStagingAreaDir
-----------------------------------------------------------------------------------------------------------------
Key: MAPREDUCE-1319
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1319
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: client
Affects Versions: 0.22.0
Reporter: Devaraj Das
Fix For: 0.22.0
MAPREDUCE-181 introduced ClientProtocol.getStagingAreaDir. It'd be good to
refactor the client side where it infers the JobTracker's filesystem, etc.
based on this. Seems like the client needn't invoke ClientProtocol.getSystemDir
at all.
