-------------------------------------
Summary: Shuffle server listen queue is too small
Key: MAPREDUCE-6763
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6763
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Reporter: Jason Lowe
Assignee: Jason Lowe
ShuffleHandler doesn't specify a listen queue length for the server port, so it
ends up getting the default listen queue length of 50. This is too small to
handle bursts of shuffle traffic on large clusters. It's also inconsistent
with the default Hadoop uses for RPC servers (default=128).
