The Jenkins result looks good to me. I will commit it shortly. Ignore the checkstyle issue "Variable 'rpcSlowCalls' must be private and have accessor methods." since it is inconsistent with the existing code. > 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 > Attachments: Callers of WritableRpcEngine.call.png, HADOOP-12325.001.patch, HADOOP-12325.002.patch, HADOOP-12325.003.patch, HADOOP-12325.004.patch, HADOOP-12325.005.patch, HADOOP-12325.005.test.patch, HADOOP-12325.006.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
