Leonard Xu commented on FLINK-18570:
------------------------------------
The same reason with my previous investigation, unfortunately I didn't
reproduce this on my many azure builds(I added some log output), [~rmetzger]
Could we add add a little log for `AbstractTableInputFormat` as a hotfix ?
Once the test failed again, we can obtain more information to help fix it.

Caused by: java.io.IOException: Expecting at least one region.
