> HA: Autopopulate standby name dirs if they're empty

> Key: HDFS-2731
> URL: https://issues.apache.org/jira/browse/HDFS-2731
> Project: Hadoop HDFS
> Issue Type: New Feature
> Components: ha
> Affects Versions: 0.24.0
> Reporter: Aaron T. Myers
> Assignee: Todd Lipcon
> Fix For: 0.24.0, 0.23.3

> Attachments: hdfs-2731.txt, hdfs-2731.txt, hdfs-2731.txt

> To setup a SBN we currently format the primary then manually copy the name
> dirs to the SBN. The SBN should do this automatically. Specifically, on NN
> startup, if HA with a shared edits dir is configured and populated, if the
> SBN has empty name dirs it should downloads the image and log from the
> primary (as an optimization it could copy the logs from the shared dir). If
> the other NN is still in standby then it should fail to start as it does
> currently.
