Joydeep Sen Sarma commented on HIVE-2051:
-----------------------------------------
based on: http://www.ibm.com/developerworks/java/library/j-jtp05236.html
it seems that the right thing to do here is to catch the interruptedexception
and then call Thread.currentThread.interrupt() (grep for 'swallow interrupt' in
this article).
we could also rethrow it - but the problem then will merely be punted to the
higher layer (which probably will ignore it as well)
> getInputSummary() to call FileSystem.getContentSummary() in parallel

> getInputSummary() now call FileSystem.getContentSummary() one by one, which
> can be extremely slow when the number of input paths are huge. By calling
> those functions in parallel, we can cut latency in most cases.
