Amir Langer created HDFS-5732:
---------------------------------
Summary: Separate memory space between BM and NN
Key: HDFS-5732
URL: https://issues.apache.org/jira/browse/HDFS-5732
Project: Hadoop HDFS
Issue Type: Sub-task
Components: namenode
Reporter: Amir Langer
Change created APIs to not rely on the same instance being shared in both BM
and NN. Use immutable objects / keep state in sync.
BM and NN will still exist in the same VM work on a new BM service as an
independent process is deferred to later tasks.
Also, a one to one relation between BM and NN is assumed.
This task should maintain backward compatibility.
