Thanks a lot to Tsz-Wo for helping create branch-2_tmp branch, already refer to it and cherry-pick part of pull request to branch-2.
All JIRAs proposed on the mailing list have now been merged into branch-2. William, could you help check the brnach-2 to see if there are other JIRAs that Iotdb needs. Thank you in advance! If all goes well, I hope close this discussion and launch a 2.4.1 release tomorrow. -Yaolong
