Akira AJISAKA commented on HDFS-8306:
-------------------------------------
Thanks [~eddyxu] for creating the patch. Could you skip output the contents of
a feature (ex. quota by storage type) instead of throwing IOException if the
layout version of the fsimage does not support the feature?

> Currently, in the {{hdfs oiv}} XML outputs, not all fields of fsimage are
> outputs. It makes inspecting {{fsimage}} from XML outputs less practical.
> Also it prevents recovering a fsimage from XML file.
> This JIRA is adding ACL and XAttrs in the XML outputs as the first step to
> achieve the goal described in HDFS-8061.
