Hello @Menyawy

Thanks for using Cloudera Community. The Error [1] indicates your Team is using CDH v5.x using HBase v1.x. In the concerned release, We have limited choices to ensure "hbase:namespace" Table Region is assigned correctly as shared below:

(I) Easier Yet Not-Always-Successful Option:

1) Shutdown HBase Service 2) echo "rmr /hbase" | hbase zkcli (From HMaster Node) 3) Start HBase Service 4) sudo hbase hbase hbck -fixAssignments

(II) Review whether any of the "hbase:namespace" Table Region files are reporting MissingBlockException. If Yes, We need to fix the MissingBlockException.

(III) Possible for the RegionServer Logs (Wherein the "hbase:namespace" Table Region is being assigned) would offer additional insight into the reasoning for the RegionServer being Unable to assign the "hbase:namespace" Table Region successfully. Your Team may review the concerned RegionServer Logs as well.

There may be Other Options, yet such Inconsistencies are better handled in HBase 2.x [1] & your Team should plan for using HBase v2.x soon.

Regards, Smarak
