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).
> Modify ShuffleHandler to support Keep-Alive
