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 altogether.
This JIRA tracks this improvement, alongwith a few more minor bugfixes that were found during Ranger-WASB testing.
