-----------------------------------
Summary: Improve RPC server throughput
Key: HADOOP-9953
URL: https://issues.apache.org/jira/browse/HADOOP-9953
Project: Hadoop Common
Issue Type: Improvement
Components: ipc
Affects Versions: 2.0.0-alpha, 3.0.0
Reporter: Daryn Sharp
Assignee: Daryn Sharp
Bottlenecks in the RPC layer are in part holding back the performance of the
NN. Even under very heavy load, the NN usually can't saturate more than a few
cores even with load patterns dominated by read ops.
This will be an umbrella for issues discovered.
