----------------------------------------
Summary: CLONE - Add immutable entries in to the DoubleBuffer for
Volume requests.
Key: HDDS-2344
URL: https://issues.apache.org/jira/browse/HDDS-2344
Project: Hadoop Distributed Data Store
Issue Type: Task
Reporter: Bharat Viswanadham
Assignee: Bharat Viswanadham
Fix For: 0.5.0
OMBucketCreateRequest.java L181:
omClientResponse =
new OMBucketCreateResponse(omBucketInfo,
omResponse.build());
We add this to double-buffer, and double-buffer flushThread which is running in
the background when picks up, converts to protoBuf and to ByteArray and write
to rocksDB tables. So, during this conversion(This conversion will be done
without any lock acquire), if any other request changes internal structure(like
acls list) of OMBucketInfo we might get ConcurrentModificationException.
