-------------------------------------
Hi gewen, please provide more info about the issue (hadoop environment, kylin
version etc), and how to reproduce; only a stacktrace sometimes is poor for a
developer to understand the issue. If you can solve the issue and contribute a
patch, that will be welcomed.
