you may try this
set hive.mapred.partitioner=
org.apache.hadoop.mapred.lib.TotalOrderPartitioner;
set total.order.partitioner.natural.order=[false|true];
set total.order.partitioner.path=[path];

thrift server and CDH issue?
Posted by hadoopman <ha...@gmail.com>.
I recall recently reading somewhere on cloudera's web site that it was
not recommended to run more than one thrift server connecting to hive
however it's been a couple months since reading this. I'm still digging
to find the article and was curious perhaps someone here can provide
some insight on this?
Perhaps I misread it.
Basically we're looking at setting up a thrift server port for every
hive user so it would be easier for us to identify who kicked off a job.
Thanks!
