> Column in table is defined with upper case or mixed case, when do update command with
verbatim column names, update doesn't update the value. when do update with all lower case
column names, it works.
> STEPS TO REPRODUCE:
> create table testable( a string, Bb string, c string)
> clustered by (c) into 3 buckets
> stored as orc
> tblproperties("transactional"="true");
> insert into table testable values ('a1','b1','c1), ('a2','b2','c2'), ('a3','b3','c3');
> update table testable set Bb='bb';
> job finishes, but the values are not really updated.
> update table testable set bb='bb'; it works.
