Chapter 8. Troubleshooting DLM
To verify that your environment meets the requirements for DPS, see Planning for a DPS Installation and the Hortonworks Support Matrix.
Endpoint is unreachable
DLM does not support updating any cluster endpoints (HDFS, Hive, Ranger, or DLM Engine). If an endpoint must be modified, contact Hortonworks Support for assistance.
Ranger UI does not display deny
policy items
If you need to view deny
policy details related to a DLM
replication policy, you need to use the Ranger UI. However, when a policy with deny
conditions is created on Ranger-admin in a replication relationship, the Policy Details
page in Ranger does not display the deny policy items. To make the policy visible,
update the respective service-def
with
enableDenyAndExceptionsInPolicies="true"
option.
