Prasanth Jayachandran commented on HIVE-19629:
----------------------------------------------
branch-3 has several existing failures (refer HIVE-19881, HIVE-19739). The
branch-3 failures are same as the ones in HIVE-19881 and HIVE-19739. I am not
sure the test changes that went in for master also went into branch-3 that
could have solved the branch-3 test issues (timeout changes, tmp directory
changes, retry changes).
