Hi,all
I encountered a thorny problem:
Early in the morning，I built a time-consuming cube，then caused memory leak,
and kylin been killed . After i restarted the kylin ,when I click on the
monitor tag on the page, remind me:failed to load jobs. And the log as
below:

The jobs of other projects is ok.I can see other projects' jobs in web page.
In addition, I can still query in this project.
First,I thought it was HBase's problem. Then i restart hbase.
But the problem remains unsolved,then i restarted hadoop habse zookeeper
hive kylin , the problem still exists!
How can i resolve this problem?If any body has idea about this problem ,
please help me ,and if anyone need more logs, i also can give more logs.
Thanks a lot.

What's your Kylin version? Line number matters to trace down NPE.
