Hi [~Tao Yang]
A couple of comments
1. Can we move code
{code:java}
userLimitPerSchedulingMode = preComputedActiveUserLimit.get(nodePartition);
{code}
to the first loc to execute after the write lock?
2. Line 572, should it be {{preComputedAllUserLimit}} instead of {{preComputedActiveUserLimit}}?
Thanks
