[jira] [Created] (HDDS-2701) Avoid read from temporary chunk file
in datanode
Lokesh Jain created HDDS-2701:
---------------------------------
Summary: Avoid read from temporary chunk file in datanode
Key: HDDS-2701
URL: https://issues.apache.org/jira/browse/HDDS-2701
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: Ozone Datanode
Reporter: Lokesh Jain
Assignee: Lokesh Jain
Currently we try reading chunk data from the temp file if chunk file does not exist. The fix was added in HDDS-2372 due to race condition between readStateMachineData and writeStateMachineData in ContainerStateMachine. After HDDS-2542 is fixed the read from the temp file can be avoided by making sure that chunk data remains in cache until the chunk file is generated.
