----------------------------------
Summary: Support passing Hadoop context to Ratis
Key: HDDS-16497
URL: https://issues.apache.org/jira/browse/HDDS-16497
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Ivan Andika
Assignee: Ivan Andika
While working on HDDS-15089, encountered an NPE issue that was caused by null
Server.getRemoteUser() in OzoneManager#getS3VolumeContext. This reason is that
Ratis would call StateMachine#query in a separate thread (under
RaftServerImpl#clientExecutor). Therefore, the ThreadLocal CurrCall which is
used by Server.getRemoteUser(). This affects all read requests that require
using ThreadLocal one way or another.
We need a way to propagate the ThreadLocal context to the StateMachine#query.
*Note this suggests that follower read feature is not production ready until
this is resolved.*
