Rajesh Balamohan commented on TEZ-988:
--------------------------------------
[~kamrul] I believe the comments in the code caused the confusion. keep-alive
can be enabeld clusterwide by setting
"mapreduce.shuffle.connection-keep-alive.enable" (MAPREDUCE-5787). As per
mapreduce-5787, one can enable/disable keep-alive by passing it via the URL
(i.e keepAlive=true or keepAlive=false). I will rephrase the comments in the
code and reupload it.
> http.maxConnections needs to be configurable in Tez Fetcher & read from
> errorstream to make the connection reusable

> 1. Currently http.maxConnections is set to 5 (default). Make this
> configurable in Fetcher.java. This will help in running larger queries
> 2. ErrorStream has to be read completely in order to make the connection
> reusable (when keepAlive is enabled). Currently, we do not read error stream.
