Description

Per SOLR-5565, ZooKeeper session timeout should have been raised to 30s. This was changed in the solr.xml example but it was not changed in the solr script, which has this:

if [ -z "$ZK_CLIENT_TIMEOUT" ]; then
    ZK_CLIENT_TIMEOUT="15000"
  fi

And for solr.cmd:

 IF "%ZK_CLIENT_TIMEOUT%"=="" set "ZK_CLIENT_TIMEOUT=15000"

So regardless of what is in solr.xml, if ZK_CLIENT_TIMEOUT is not set, it will be overridden to 15,000. I'd think this should be raised to 30,000 or removed entirely to fall back on the solr.xml's behavior. [e-mail] is this correct?
