FYI starting hdp 2.6 you we have the import/export functionality directly on the ranger admin ui. 1. Is it required to have present all the users who are belonging to cluster A ranager policy for hdfs ? Yes, otherwise the policies for missing users wont be added. 2. what could lead to failure of the policies while importing like If policy id or name is same ? There is an overwrite checkbox you can select. If checked the policies with same name will be overwritten.

@Victor Usually a restart of the interpreter also kills the yarn application. Check on RM UI, there should be a yarn application running for the interpreter. If you kill the yarn application then you will probably stop this. I see code is pretty simple. To debug you should check the spark2 interpreter log and yarn application log to find out what is happening. ... View more

@Eric Richardson By using {USER} instead of {OWNER} you could come up with the following solution: With the above policy users will be able to: 1. Use database testdb; 2. Users will be able to create tables. With the condition that table names must end in underscore username _{USER}. 2. Show tables that finish with their username only. For example: show tables; +---------------+--+ | tab_name | +---------------+--+ | t2_falbani | | test_falbani | +---------------+--+ ## Users wont see any other tables unless another policy grants them permissions 3. Users will have full control over the tables ending in underscore username _{USER} - And won't be able to perform any operations in any other tables unless there is another policy that grants them permissions. Hopefully this will help you address your requirement. Please let me know if this helps.

@Prachi Sharma I think you should try something like this: ${anyDelineatedValue("${IncludeSchemaList}", ","):equals("${db.table.schema}"):and(anyDelineatedValue("${ExcludeTableList}", ","):equals("${db.table.schema}"):not())} while having IncludeSchemaList=dbo,hilton,archive,audit,util ExcludeTableList=couponcodes,batch_job_execution_context,batch_step_execution HTH *** If you found this answer addressed your question, please take a moment to login and click the "accept" link on the answer. ...
