Subject pipeout files
Date Fri, 07 Sep 2012 15:28:32 GMT

I am seeing like one million of these files on our hadoop cluster.

1005717 files like /tmp/hdfs/hdfs_2012082902171088341605155583849.pipeout
1005742 files like /tmp/hdfs/hive_job_log_hdfs_201208290217_1000376604.txt

My questions are:

1.   What is a .pipeout file, and can they be deleted at any time?
What might happen if a pipeout file is removed that shouldn't be

2.   Is it entirely up the admin to log rotate these?    Why aren't
they rotated by default when you install the packages?
