Re: [jira] [Created] (KYLIN-1464)
org.apache.kylin.cube.CubeInstance.getDataModelDesc throw
java.lang.NullPointerException
Posted by "Zhao, John" <yu...@ebay.com>.
By the way, I already create two simple patches for this problem.
One is handle NPE itself, the other one(KYLIN-1468) is remove DataModeDesc from projects if
saveDataModelDesc throw exceptions.
Please review it when you have time. Thanks.

Re: [jira] [Created] (KYLIN-1464) org.apache.kylin.cube.CubeInstance.getDataModelDesc
throw java.lang.NullPointerException
Posted by Hao Chen <ha...@apache.org>.
A few additional comments:
1) In REST api response, if the exception message is null like NPE, we'd
better display the exception class, otherwise kylin user have to
investigate the root cause from log.
2) Control the cube metadata during creation is a good approach, but may we
disable the invalid cube or mark the cube status as invalid instead of
influencing all the other cubes while having problem with single cube? The
invalid cube status may be caused because metadata is bad, hbase is
unstable, underly hbase table/region is not found or inconsistent and so on.
Regards,
Hao

org.apache.kylin.cube.CubeInstance.getDataModelDesc throw
java.lang.NullPointerException
Posted by "Zhao, John" <yu...@ebay.com>.
That’s right, before we store the metadata, we need make sure it already passed all the check.

Re: [jira] [Created] (KYLIN-1464) org.apache.kylin.cube.CubeInstance.getDataModelDesc
throw java.lang.NullPointerException
Posted by hongbin ma <ma...@apache.org>.
btw, is it leaving a inconsistent state in the metadata store (cube
instance exist but cube desc or model missing)? if it is, please elaborate.
In that case something needs improving int the cube create controller, etc.
