---------------------------------
Summary: Genericize format() and initializeSharedEdits() to
non-file JournalManagers
Key: HDFS-3695
URL: https://issues.apache.org/jira/browse/HDFS-3695
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ha, name-node
Affects Versions: QuorumJournalManager (HDFS-3077)
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Currently, the "namenode -format" and "namenode -initializeSharedEdits"
commands do not understand how to do anything with non-file-based shared
storage. This affects both BookKeeperJournalManager and QuorumJournalManager.
This JIRA is to plumb through the formatting of edits directories using
pluggable journal manager implementations so that no separate step needs to be
taken to format them -- the same commands will work for NFS-based storage or
one of the alternate implementations.
