HA: Checkpointing in an HA setup
--------------------------------
Key: HDFS-2291
URL: https://issues.apache.org/jira/browse/HDFS-2291
Project: Hadoop HDFS
Issue Type: Sub-task
Components: name-node
Affects Versions: HA branch (HDFS-1623)
Reporter: Aaron T. Myers
Assignee: Todd Lipcon
Fix For: HA branch (HDFS-1623)
We obviously need to create checkpoints when HA is enabled. One thought is to
use a third, dedicated checkpointing node in addition to the active and standby
nodes. Another option would be to make the standby capable of also performing
the function of checkpointing.
