[GitHub] [hadoop] slfan1989 commented on pull request #4367: HDFS-16600. Fix deadlock on DataNode side.

URL: https://github.com/apache/hadoop/pull/4367#issuecomment-1146798609

   @ZanderXu  I found that some tests of Junit Test of HDFS (DN) sometimes succeed and sometimes fail, but there is no way to judge whether it is related to DeadLock. How do you judge the occurrence of DeadLock?
   
   @MingXiangLi HDFS-16534 is a very big change, which will greatly help the performance improvement of DN, but ZanderXu has already proposed 2 Jiras for this change. Can you help to re-examine this HDFS-16534, if it is separate each time The commit fixes pr, worried that it will bring more problems.
