             Summary:  Kylin should change the default folder from /tmp to user configurable destination
                 Key: KYLIN-880
                 URL: https://issues.apache.org/jira/browse/KYLIN-880
             Project: Kylin
          Issue Type: Improvement
            Reporter: Aroop Maliakkal


Kylin stores the table snapshots in /tmp folder by default. It is pretty normal to do cluster cleanups during cluster binary upgrades. This will cause all the cubes table_snapshot files to be lost from the cluster and it will throw errors while building cubes. To avoid this, we should ensure the user provides the kylin.hdfs.working.dir rather than assuming /tmp .
