--------------------------------
Summary: Provide an alternative offline file system analysis tool
Key: HDFS-6384
URL: https://issues.apache.org/jira/browse/HDFS-6384
Project: Hadoop HDFS
Issue Type: Improvement
Affects Versions: 2.5.0
Reporter: Kihwal Lee
Priority: Critical
Per discussion in HDFS-6293, we need an alternative way of analyzing file
system offline. Some use cases can be covered by post-processing the new
PB-based fsimage without consuming much resources, but others may need a way to
efficiently generating fully constructed name space.
Once we have a better solution, we should deprecate NN's ability to save its
partial state in the old fsimage format.
