I have added the below property in hdfs-site.xml to check ACL's in hdfs filesystem and just restart the hdfs , yarn services in ambari resolves the issue.

<name>dfs.namenode.acls.enabled</name> <value>true</value>

</property>

@subhash parise

See this

org.apache.hadoop.ipc.RemoteException(org.apache.ranger.authorization.hadoop.exceptions.RangerAccessControlException): Permission denied: principal{user=hbase,groups: [hadoop]}, access=null, /apps/hbase/data at

I am guessing that you enabled the ranger plugin for HBASE.

User hbase does not have permission to access /apps/hbase/data

subhash_parise3 · ‎01-29-2016

Hi Neeraj,

hbase user is having the permission to access /apps/hbase/data

please see the below output:

[hdfs@eu-lamp-dev-xl-0019-hadoop-sec-master hbase]$ hdfs dfs -ls /apps/hbase

Found 2 items

drwxr-xr-x - hbase hdfs 0 2016-01-11 12:18 /apps/hbase/data

nsabharwal · ‎01-29-2016

@subhash parise My bad as I did not see the full details. In future, you can click code button after pasting the error log for better formatting.

Can you check HDFS and HBASE policies in ranger console ?

subhash_parise3 · ‎01-29-2016

@Neeraj Sabharwal

Please find the attachment for ranger hbase policy ranger.png. did n't find any hdfs related policy in ranger console.

nsabharwal · ‎01-29-2016

@subhash parise Could you enable HDFS plugin and then try to bring up HBASE? please...

nsabharwal · ‎01-29-2016

@subhash parise As per my understanding, if you enable HDFS plugin for ranger then you don't need to set that parameter. It would be nice to test this.

aervits · ‎01-29-2016

@subhash parise

do you have a group called hadoop? Can you make sure hbase user belongs to the hadoop group? Confirm it belongs to hdfs group as well.

subhash_parise3 · ‎01-29-2016

I have added the below property in hdfs-site.xml to check ACL's in hdfs filesystem and just restart the hdfs , yarn services in ambari resolves the issue.

Thanks for the final post. I have accepted this as best answer.
