Subject [jira] [Updated] (MAPREDUCE-5787) Modify ShuffleHandler to support Keep-Alive
Date Thu, 13 Mar 2014 10:12:50 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-5787?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Rajesh Balamohan updated MAPREDUCE-5787:
----------------------------------------

    Attachment: MAPREDUCE-5787-2.4.0-v2.patch

- Keep-Alive is disabled by default.
- Keep-Alive can be enabled by setting "mapreduce.shuffle.enable.keep.alive"
- Timeout parameter can be adjusted using "mapreduce.shuffle.enable.keep.alive.timeout"
- There is add-on facility wherein Keep-Alive can be enabled via request URL by adding keepAlive=true
parameter.  This will allow frameworks like Tez to benefit from Keep-Alive connections &
 without affecting any MR jobs (for which the keep-alive connections are disabled by default).
