---------------------------
Summary: Namenode INITIALIZESHAREDEDITS should be able to
initialize all shared storages
Key: HDFS-3765
URL: https://issues.apache.org/jira/browse/HDFS-3765
Project: Hadoop HDFS
Issue Type: Improvement
Components: ha
Affects Versions: 2.1.0-alpha, 3.0.0
Reporter: Vinay
Assignee: Vinay
Currently, NameNode INITIALIZESHAREDEDITS provides ability to copy the edits
files to file schema based shared storages when moving cluster from Non-HA
environment to HA enabled environment.
This Jira focuses on the following
* Generalizing the logic of copying the edits to new shared storage so that any
schema based shared storage can initialized for HA cluster.
* Ability to Initialize new shared storage from existing shared storage when
moving from One shared storage to another shared storage (Might be because of
cost, performance, etc. For ex: Moving from NFS to BKJM/QJM).
