@MrNicen firstly, You will need to check the RS log of l230-n2.<SERVER>. As per the WARn, the region is already reported as OPEN by the same RS on which its trying again to open and going into a OPENING state. It seems there are SCPs/ multiple assign procedures are running in the backend trying to open a region that is already open.  Considering that you are on a version that can neither use hbck2 jar nor the hbck1 commands,  you can give try the below : 1) Stop both the Master 2) Move the contents of MasterProcWALs to a backup location # hdfs dfs -mv /hbase/MasterProcWALs/* /tmp/ 3) Start the Masters. If the above doesn't solve the issue, I suggest raising a support case with Cloudera to review the logs. ... View more

To enable Ranger authorization for HDFS on the same cluster we should not select the Ranger service dependency but we should select the 'Enable Ranger Authorization' checkbox instead of the Ranger service under HDFS. In the base cluster, even if you select / check the box for "Ranger_service", the CM seem to indicate saving configuration successfully, but that box will never be checked, and a warning message will be logged in CM server logs indicating "CyclicDependencyConfigUpdateListener - Unsetting dependency from service hdfs to service ranger to prevent cyclic dependency". Refer the below article which is for Solr-Ranger dependency. https://my.cloudera.com/knowledge/WARN-quotUnsetting-dependency-from-servicequot-when-Ranger?id=329275 ... View more

@LLL_ Both the information be it either from hadoop cmdline or from Web UI will come from the in-memory data structures that the Namenode stores in its metadata. The NameNode maintains this metadata in its memory for fast access. So the fsimage is your persistent metadata that the Namenode reads while starting up and keeps this information in its memory to present a dynamic state of the file system when the user queries via Web UI. ...
