Summary: RPC Metrics : Add the ability track and log slow RPCs
Key: HADOOP-12325
URL: https://issues.apache.org/jira/browse/HADOOP-12325
Project: Hadoop Common
Issue Type: Improvement
Components: ipc, metrics
Affects Versions: 2.7.1
Reporter: Anu Engineer
Assignee: Anu Engineer
This JIRA proposes to add a counter called RpcSlowCalls and also a
configuration setting that allows users to log really slow RPCs. Slow RPCs are
RPCs that fall at 99th percentile. This is useful to troubleshoot why certain
services like name node freezes under heavy load.
