     [ https://issues.apache.org/jira/browse/HADOOP-17608?focusedWorklogId=573294&page=com.atlassian.jira.plugin.system.issuetabpanels:worklog-tabpanel#worklog-573294 ]

ASF GitHub Bot logged work on HADOOP-17608:
-------------------------------------------

                Author: ASF GitHub Bot
            Created on: 29/Mar/21 02:35
            Start Date: 29/Mar/21 02:35
    Worklog Time Spent: 10m 
      Work Description: aajisaka opened a new pull request #2828:
URL: https://github.com/apache/hadoop/pull/2828


   When running all the unit tests in TestKMS by `mvn test -Dtest=TestKMS` instead of specifying a test case (e.g., `mvn test -Dtest=TestKMS#testStartStopHttpsPseudo`) , NPE occurs because there may be some active null threads or some active threads are removed after allocating the active thread list.
