[jira] [Created] (HDFS-3438) BootstrapStandby should not require a
rollEdits on active node
Todd Lipcon created HDFS-3438:
---------------------------------
Summary: BootstrapStandby should not require a rollEdits on active node
Key: HDFS-3438
URL: https://issues.apache.org/jira/browse/HDFS-3438
Project: Hadoop HDFS
Issue Type: Improvement
Components: ha
Affects Versions: 2.0.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Currently, BootstrapStandby uses a rollEdits() call on the active NN in order to determine the most recent checkpoint and transaction ID. However, this means that you cannot bootstrap a standby when the active NN is in safe mode -- i.e you have to start the whole cluster before you can bootstrap a new standby. This makes the workflow to convert an existing cluster to HA more complicated. We should allow BootstrapStandby to work even when the NN is in safe mode.
