------------------------------
Summary: Fix tests using MiniOzoneCluster for its memory related
exceptions
Key: HDDS-2186
URL: https://issues.apache.org/jira/browse/HDDS-2186
Project: Hadoop Distributed Data Store
Issue Type: Sub-task
Reporter: Li Cheng
After multi-raft usage, MiniOzoneCluster seems to be fishy and reports a bunch
of 'out of memory' exceptions in ratis. Attached sample stacks.
