> Thrift servers use connection cache and we drop connections after hbase.thrift.connection.max-idletime
milliseconds from the last time a connection object was accessed. However, we never update
this last accessed time on scan path. 
> By default, this will cause scanners to fail after 10 minutes, if the underlying connection
object is not being used along other operation paths (like put).
