No, there is no downside to it. Making the default value for
"tez.runtime.shuffle.keep-alive.max.connections" to 20.
> 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.
