Hello @SDL Thanks for using Cloudera Community. As you have used InfraSolr & HDP tag, Kindly confirm the HDP Version wherein the concerned issue is being observed. Additionally, Link [1] is an excellent article on the concerned Topic & may offer any missing details. - Smarak [1] https://community.cloudera.com/t5/Community-Articles/Solr-TTL-Auto-Purging-Solr-Documents-Ranger-Audits/ta-p/247920

Hello @SurajP Thanks for using Cloudera Community. You mentioned the SQL works in Zeppelin Notebook on HDP v3.0 while doesn't work on HDP v2.6. The error posted by you points to the fact that the Table "enrichedEvents" isn't found. The same isn't likely caused by any Configuration issues, rather pointing to the absence of the Table. You haven't mentioned the Interpreter used, yet would request you to query the Metadata to confirm if the concerned Object "enrichedEvents" is listed in the Metadata. Accordingly, you can proceed with the SQL. - Smarak

Hello @vidanimegh Thanks for using Cloudera Community. To answer your query, (I) There is no dependency between the 2 Services with respect to which one should be installed first. If you have to pick, First Authenticate & then, Authorise i.e. Setup Kerberos first before installing Ranger. (II) Again, no caution required as there is no explicit dependency. (III) For HDP Stack, there is no requirement to enable TLS/SSL before Kerberos. Recommend to perform the Steps (Enabling Kerberos | Enabling Ranger | Enable TLS/SSL) via Ambari for easier management. Let us know if you have any further queries. - Smarak

Hello @Anks2411 Thanks for sharing the Cause. To your query, Yes, HBase Balancer should be enabled & "balance_switch" should be set as "true". Once you have no further queries, Kindly mark the Post as Solved as well. - Smarak

Hello @TGH Yes, After doing any HBCK2 Changes, Restart the Service as the Components have a Cached Version of the Metadata as well. Let us know how things goes. - Smarak

Hello @ASIF123 Thanks for using Cloudera Community. For the Orphan Region, We need to confirm the Source. Will recommend checking the Region IDs in "hbase:meta" Table & HBase Data Directory. If the Region IDs aren't present in "hbase:meta" Table with only Region Directory present, Check if the Region Directory has any StoreFiles or "recovered.edits" file. If no StoreFiles or "recovered.edits" files are present, It's likely the Regions are part of Split or Merge (Verifiable by HMaster Logs) & we can safely sideline the Region Directories. If no StoreFiles are present yet "recovered.edits" files are present, Again check if the Regions are part of Split or Merge (Verifiable by HMaster Logs), Use WALPlayer to replay the "recovered.edits" files to be on safer side & then, sideline the Region Directories. - Smarak

Hello @Anks2411 Thanks for using Cloudera Community. You shall need to check the Logs of "cdh-dn-28.prod.mcs.az-eastus2.mob.nuance.com" RegionServer to confirm the reasoning for Region "8808c0e1917bf0b4acea2d83d9548463" being FAILED_CLOSE. For any Region to be moved from RegionServer A to RegionServer B, the Region has been to closed on RegionServer A before being opened on RegionServer B. In your case, the Region is failing to close on RegionServer A & the Logs would confirm the reasoning for the same. - Smarak

@TGH No worries, if you are planning to drop the Table anyhow, Let's use the following approaches: 1. You (Your previous Team) have deleted the Table Level Directories from HDFS. 2. In HBase:Meta, We have 1 Row per Table Region & 1 Row for Table as well. 3. Use "get 'hbase:meta','<RegionID RowKey>'". Note that your Team can get the Scan Output to check the format of the RowKey for the concerned Table, which includes the RegionID. 4. After confirming the Output from "get" Command, Use the "deleteall" Command with the same Argument to remove the Rows of Table's Region. Finally, Remove the Table Level Info as well. 5. Restart the HBase Service to clear the Cache as well. Recommend to test the above on 1 Sample Table (Create Table > Remove Region Directory > Remove Meta Info > Restart HBase > Check HBCK Output). - Smarak

Hello @TGH I downloaded the HBCK2 Tool from the Steps shared & I could see the "extraRegionsInMeta" listed in the "README.md" file. - Smarak
