nichunen updated KYLIN-3653:
----------------------------
Description:
The root cause is in org.apache.kylin.common.util.HiveCmdBuilder#build

} finally {

logger.debug("The SQL to execute in beeline: \n" + hql);

{code}
A temp hql file will be created when creating flat table, the file name is the
current time stamp. But if two jobs triggered with same time, there will be
only one file, and jobs may be failed
