             Summary: unclosed hive session cause too many temp file
                 Key: KYLIN-4225
                 URL: https://issues.apache.org/jira/browse/KYLIN-4225
             Project: Kylin
          Issue Type: Improvement
            Reporter: ZhouKang


in org.apache.kylin.metrics.lib.impl.hive.HiveProducer, when need add a new 
partition to metrics data, a SessionState will be started , and unclosed after 
use.

which cause many temp dir in HDFS (\{ROOT}/tmp/hive/xxx).

I think the session should be stoped manually
