Gabor Arki commented on KYLIN-4348:
-----------------------------------
We just upgraded to 3.1.0 release but we are still seeing this issue. After a
short time, we get all of the already started "STREAM CUBE" jobs stuck in
whichever state they were (no progress in the last 8 hours), while all new jobs
are stuck at pending state, not making any progress. Yet according to yarn, no
jobs are running or have been submitted for the past 8 hours. In the logs we
are still seeing:
