Ivan Andika updated HDDS-16222:
-------------------------------
Description:
We have incidents due to wrong usage of notifyStatusChanged in Ozone.
* HDDS-11750: This is caused by deadlock when notifyStatusChanged submits
another Ratis
* HDDS-16029: This is caused by notifyStatusChanged blocking during
ContainerBalancer Thread.join
One idea is to write a PMD rule to statically detect the following issues. See
[https://pmd.github.io/pmd/pmd_userdocs_extending_writing_rules_intro.html]
Another idea is to use https://github.com/reactor/BlockHound
