Hello @RammiSE 

 

Your Post is being replied a bit late, yet I am posting a response anyways. Assuming your Team has resolved the Issue, Appreciate your Team sharing the details in the Post for wider audience. 

 

For HMaster to be Initialised, "hbase:meta" & "hbase:namespace" Table Region needs to be Online. In your previous thread, the HMaster is reporting "hbase:meta" isn't Online [1]. As such, Use the HBCK2 JAR to assign the "hbase:meta" Region "1588230740" first & review (Via HBase UI) whether Regions are being assigned successfully. It's feasible the "hbase:namespace" Table Region would also reporting similar tracing, in which case your Team needs to use HBCK2 JAR to assign the "hbase:namespace" Region. Restarting HMaster after manually performing HBCK2 Assign isn't required always, yet the same won't harm as well. 

 

Regards, Smarak

Hi @RammiSE , Based on the exception, the hbase:namespace table is not online. You will need to assign the namespace region to bring up the Hbase Master.

@RammiSE you will need to assign the respective namespace region ID by checking the Hbase Master log using the hbck2 jar
