Thanks, Varun! > Remove sleep between IPC client connect timeouts > ------------------------------------------------ > > Key: HADOOP-9503 > URL: https://issues.apache.org/jira/browse/HADOOP-9503 > Project: Hadoop Common > Issue Type: Improvement > Components: ipc > Affects Versions: 2.0.5-beta > Reporter: Varun Sharma > Assignee: Varun Sharma > Priority: Minor > Fix For: 2.0.5-beta > > Attachments: 9503.patch > > > HADOOP-9106 introduced a configurable retry timeout when there are socket timeouts errors. > Since the IPC client is used by a wide variety of applications including realtime/online ones (like hbase + hdfs), we sometimes need fast fail timeouts which are < 3 seconds. Achieving such a timeout for connect is very difficult with a 1 second sleep in b/w retries. It would be good to remove this sleep. -- This message is automatically generated by JIRA.
