---------------------------------
Summary: Remove false-positive error logs from LeaseManager
Key: HDDS-4526
URL: https://issues.apache.org/jira/browse/HDDS-4526
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Reporter: Marton Elek
There is an error log which can be seen frequently in the log:
{code}
2020-11-30 15:35:58,539 [CommandWatcher-LeaseManager#LeaseMonitor] ERROR
lease.LeaseManager (LeaseManager.java:run(238)) - Execution was interrupted
java.lang.InterruptedException: sleep interrupted
at java.lang.Thread.sleep(Native Method)
at
org.apache.hadoop.ozone.lease.LeaseManager$LeaseMonitor.run(LeaseManager.java:234)
at java.lang.Thread.run(Thread.java:748)
{code}
This log is introduced by HDDS-2561 to make Sonar happy, but it was not
required as LeaseManager use the thread interrupt intentionally.
For a proper fix we can keep the logging on WARN level AND replace thread
interrupts with thread notify/wait.
