[jira] [Created] (HDFS-14112) Avoid recursive call to external
authorizer for getContentSummary.
Jitendra Nath Pandey created HDFS-14112:
-------------------------------------------
Summary: Avoid recursive call to external authorizer for getContentSummary.
Key: HDFS-14112
URL: https://issues.apache.org/jira/browse/HDFS-14112
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Jitendra Nath Pandey
Assignee: Tsz Wo Nicholas Sze
HDFS-12130 optimizes permission check, and invokes permission checker recursively for each component of the tree, which works well for FSPermission checker.
But for certain external authorizers it may be more efficient to make one call with {{subaccess}}, because often they don't have to evaluate for each and every component of the path.
