Please try enabling debug and check the ranger admin logs for issue. Also check hbase logs for errors if any -

ranger debug -

vi /usr/hdp/current/ranger-admin/ews/webapp/WEB-INF/log4j.xml

Modify - <priority value="info" />

To - <priority value="debug" />

And restart ranger.

Try testing the Hbase repository connection again.

Is the correct hbase-site.xml accessible (on the classpath) ?

Can you pastebin the stack trace when timeout is encountered ?

Which version of HDP are you using ?

Thanks

Go to custom ranger-hbase-security section in ambari and add the following. These setting in ranger will help you modify the read and connection timeout. Please try increasing this and see how it goes?

ranger.plugin.hbase.policy.rest.client.connection.timeoutMs=120000

ranger.plugin.hbase.policy.rest.client.read.timeoutMs=30000
