HIVE-26493: Hive throws error when querying a view that was created successfully
What changes were proposed in this pull request?
While creating view, if column names are specified and the view definition is enclosed within the brackets then view creation is ok but while selecting the data from view, as here user provided column names the view definition is becoming like
select col1 as c1 from ((select col1 from tab)) v0, here view definition is already enclosed within brackets and we also adding an extra brackets again, which is causing compile failure.So as a part of fix, if view definition is already enclosed within brackets then not adding the brackets again.
Why are the changes needed?
