Doug Cutting updated HADOOP-2344:
---------------------------------
Status: Open (was: Patch Available)
I think you mean to override Thread#run(), not Thread#start(), no?
Also, do we need both ShellUtil & ShellCommand? It would seem less error prone
to have a single utility for executing command lines.
I think this is a bug worth fixing. In a previous version of DF.java, I recall
finding that failing to explicitly close all streams could cause file
descriptor leaks. Now it seems that in the current version streams are no
longer closed again. And reading process output before checking for exit
status also seems prudent.
> Free up the buffers (input and error) while executing a shell command before
> waiting for it to finish.

> found that this might be a possible cause.
