> This improvement seeks to simplify the WASB-Ranger policy model -- both the policy specification
and policy enforcement.
> More specifically, WASB-Ranger checks do not follow the same policy model and enforcement
as Ranger-HDFS.
> Ranger-HDFS hands off to HDFS-ACLs when a policy-match is not found. The handoff requires
the Ranger policies follow the same model as HDFS-ACLs. This is not true with Ranger+WASB.
> We seek to simplify the policy specification and enforcement by dropping the 'x' bit
> This JIRA tracks this improvement, alongwith a few more minor bugfixes that were found
during Ranger-WASB testing.
