java.io.FileNotFoundException: shuffle
Hi,
I am running my spark job on Yarn; using latest code from master
branch..synced few days back. I see this IO Exception during shuffle(in
resource manager logs). What could be wrong and how to debug it? I have seen
this few times before; I was suspecting that this could side effect of
memory pressure..but I could never figure out the root cause.
