[jira] [Created] (HDFS-15031) Allow BootstrapStandby to download
FSImage if the directory is already formatted
Danny Becker created HDFS-15031:
-----------------------------------
Summary: Allow BootstrapStandby to download FSImage if the directory is already formatted
Key: HDFS-15031
URL: https://issues.apache.org/jira/browse/HDFS-15031
Project: Hadoop HDFS
Issue Type: Improvement
Components: hdfs, namenode
Reporter: Danny Becker
Currently, BootstrapStandby will only download the latest FSImage if it has formatted the local image directory. This can be an issue when there are out of date FSImages on a Standby NameNode, as the non-interactive mode will not format the image directory, and BootstrapStandby will return an error code. The changes here simply allow BootstrapStandby to download the latest FSImage to the image directory, without needing to format first.
