TEZ-1341.2.patch
{code}
checkArgument((key == REPEAT_KEY || key.getClass() == keyClass),
"wrong key class: " + key.getClass() + " is not " + keyClass);
checkState(keyLength >= 0, "Negative key-length not allowed: "
+ keyLength + " for " + key);
{code}
These were the causes of the issue (Attached the profiler snapshot after the
fix).
Agreed that additional checks should not be removed as a part of this.
Reverted those changes in the latest patch.
