Hi all,
I'm seeing exceptions that look like the below in Spark 0.9.1. It looks
like I'm running out of inodes on my machines (I have around 300k each in a
12 machine cluster). I took a quick look and I'm seeing some shuffle spill
files that are around even around 12 minutes after they are created. Can
someone help me understand when these shuffle spill files should be cleaned
up (Is it as soon as they are used?)
Thanks,
Michael
