Which CDH version you are currently using?
We are experiencing the same issue and using CDH6.2.. I believe this is a bug but let me know which version you are using so that we can report the bug if needed.
As i am running the quarry , randomly i am getting an warning , /00000_0_1_copy_1 has an invalid version number: this could be due to stale metadata. try running "refresh _xml" Could not execute command: compute stats.
i am very much curious to know about the root cause and it something which is blocking my work all the time
