Hello @Khairul_Hasan Thanks for engaging Cloudera Community. Based on the Post, Your Team is receiving [1] while running the Command [2] in CDP v7.1.7. The Same Command was running with CDP v7.1.3. If you include Verbose for ClassLoading (Similar to "-verbose:class"), Your Team would confirm the Jar from which the Method is loaded. If your Team can pass the Phoenix Client & Phoenix Server jar explicitly in the ClassPath (The Path would be similar to "/opt/cloudera/parcels/<PhoenixParcelDir>/lib/phoenix/<PhoenixClientJar>" & "/opt/cloudera/parcels/<PhoenixParcelDir>/lib/phoenix/<PhoenixServerJar>"), We expect the Error to be managed. Kindly review the same & share the Outcome. Regards, Smarak [1] Can't find method newStub in org.apache.phoenix.coprocessor.generated.MetaDataProtos$MetaDataService!

Hello All, This is an older post which had a few recent followup queries. To close the loop, HBase offers multiple Tools to migrate Data from 1 Cluster to another Cluster like Snapshot, Export-Import, HashTable/SyncTable etc. Most of these Tools relies on MapReduce & uses 1 Mapper per Region of the Source Table. All these Tools works without any concerns. The only part of the ask which can't be answered accurately is the Concurrency/Job Configurations/Mapper Memory etc. These details rely on Customer's Environment Setup & the Bandwidth between the 2 Clusters. As such, Customer can run 1 such HBase MR Job & see the Outcome. Accordingly, Fine-Tune is required. If any issues are observed while performing the above HBase MR Job, Feel free to post the Q in a Community Post for fellow Community Members to review & share their thoughts. Regards, Smarak

Hello @hbasetest You wish to enable Normalizer at Cluster Level irrespective of the Table Level Setting i.e. NORMALIZATION_ENABLED be True or False. As far as I believe, We would require Table Level enabling. Having said that, If you can Open a Post on the same by using the Steps shared by @VidyaSargur, Our fellow Community Gurus can get back to you sooner, as compared to a Comment on an Article written in 2016.

Hello @achandra, This is an Old Post yet closing the same by sharing the feedback concerning your ask for wider audience. The API is failing owing to Space between "NOW-" & "7DAYS". There shouldn't be any gap between the same. In Summary, the Command is below, where Customer needs to set the HTTP(s) header, Solr Host & Solr Port accordingly. Additionally, the Example uses "ranger_audits" Collection & "evtTime" field to delete any Documents older than 7 Days: ### curl -k --negotiate -u : "http[s]://<Any Solr Host FQDN>:<Solr Port>/solr/ranger_audits/update?commit=true" -H "Content-Type: text/xml" --data-binary "<delete><query>evtTime:[* TO NOW-7DAYS]</query></delete>" Regards, Smarak

Hello @sgenchev While I am not familiar with building Charts to answer the Query, I shall share a few CLI approaches: (I) HBCK: Running "hbase hbck --details" prints [1] detailing the Regions per RegionServer. (II) Using JMX: Say, the HMaster UI is "http://HMaster1:22002/master-status". Replace "master-status" with "jmx", which prints the JSON Output. Additional filtering can be done to capture the Regions per RegionServers. Regards, Smarak [1] HBCK Output: RegionServer: RegionServer1,22101,1655811831192 number of regions: 1 RegionServer: RegionServer2,22101,1655811830393 number of regions: 1 RegionServer: RegionServer2,22101,1655811832307 number of regions: 1

Hello @cprakash Let us know if you have fixed the ConnectionRefused Error to Master1 on Port 16000. As @rki_ mentioned, Review the HMaster Logs to confirm the reasoning for ConnectionRefused. Few possible scenarios being Port 16000 is being used by any other Service Or, "master1" isn't correctly being mapped as per DNS Or, Port 16000 may be blocked. Based on the HMaster Logs, We may offer further review. As such, If the Issue persists, Share the HMaster Logs covering the concerned Stacktrace as well. If the Issue has been resolved, We shall appreciate if you can share the details into the Cause & Fix applied. Regards, Smarak
