Alan Gates commented on HIVE-8152:
----------------------------------
In UpdateDeleteSemanticAnalyzer:
It looks like you have a added an unused import (antlr.collections.AST)
At line 347, adding the null check for columnsAccessInfo. I think if this is
null we should create it rather than ignore adding the columns, as is done for
the update columns above. [~thejas]?
> Update with expression in set fails
