             Summary: Datanode goes OOM based because of segment size
                 Key: HDDS-834
                 URL: https://issues.apache.org/jira/browse/HDDS-834
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: Ozone Datanode
    Affects Versions: 0.3.0
            Reporter: Mukul Kumar Singh
            Assignee: Mukul Kumar Singh


Currently ratis segment size is set to 1GB. After RATIS-253, the entry size for a write Chunk is not  counted towards the entry being written to Raft Log.

This jira controls the segment size to 16KB which makes sure that the number of entries with WriteChunk is limited to 64. This means with 16MB chunk, the total data pending in the segment is 1GB.
