Amareshwari Sriramadasu updated MAPREDUCE-1864:
-----------------------------------------------
Attachment: patch-1864.txt
Patch removes un-initialized and unused variables : fs_, debug_,
debugFailEarly_, debugFailDuring_, debugFailLate_, jobLog_, log_, LOGNAME and
mapredKey_.
bq. If some debug statements are needed, we could add them as..
Two of the debug statements do not look relevant, so removed them. Replaced the
other one with LOG.debug.
bq. mapredKey_ is not set at all but referenced in getContext(). We need to
set it appropriately.
The variable is never set from the first version. The next line in getContext()
is adding last output. So, removed this.
Also removed new Date() from getContext(), because getContext() is called from
log message and logger will anyway prefix the log with the current time.
> PipeMapRed.java has uninitialized members log_ and LOGNAME

> PipeMapRed.java has members log_ and LOGNAME, which are never initialized and
> they are used in code for logging in several places.
> They should be removed and PipeMapRed should use commons LogFactory and Log
> for logging. This would improve code maintainability.
