Description

I build a cube but it failed in the "Build Base Cuboid Data" step, I can not get job failed email and find the stacktrace in log :
java.lang.NullPointerException

This is caused by CubingJob.getSourceRecordCount() function return null while get this job input source recode, So here need a recheck before return .
