----------------------------------------
Summary: Fix potential performance issue introduced by RANGER-1181
Key: RANGER-1737
URL: https://issues.apache.org/jira/browse/RANGER-1737
Project: Ranger
Issue Type: Bug
Components: plugins
Affects Versions: 0.7.1, 0.7.0
Reporter: Madhan Neethiraj
Fix in RANGER-1181 added fallback to native authorizer for each level -
parent/ancestor/self/subAccess. In the newly added fallback cases,
FsAction.NONE was sent to the default authorizer - which caused the default
authorizer to traverse the entire sub-tree to validate subAccess. This can
cause performance issues, if the subtree has large number of files/directories.
Calls to default authorizer should send null, instead of FsAction.NONE - this
will eliminate the unnecessary subtree traversal.
