??????[jira] [Commented] (FLINK-29877) Failed to fetch next result

[??????]

It's TableA union all TableB union all TableC.The data volume of the three 
tables is not large. They are all about hundreds. I used the hive connector to 
read the three tables. The sqlmode is default.When it's running and report a 
error:Failed to fetch next result.Then I suspected that it was a memory 
problem, so I set the related memory to a large size,But it doesn't work.Thanks
