Abhijeet Gaikwad commented on SQOOP-539:
----------------------------------------
Patch looks good to me now.
As this is just a query change at one place, I feel we can bypass review board.
For me,
ant test -Dhadoopversion=100 [success]
ant checkstyle [no errors]
In all -
+1 from my side
But we need to wait till one of the committers approves this.
> getPrimaryKeyQuery is very slow in mysql 5.0.77
