Hello @yagoaparecidoti Thanks for using Cloudera Community. Based on the Post, You encountered "Master Is Initializing" & ended up fixing the same using Command found on Internet. You ended up with few Tables in Broken State, requiring you to delete & recreate them. For documenting the Post, the Issue observed is tracked via [1]. In the HMaster Logs, We should see HBase:Meta & HBase:Namespace Region, which aren't being assigned. Sample tracing shared via [1]. Once the same happens, Using HBCK2 Jar to assign the Region being reported as Unassigned is required. The Command to be used via HBCK2 Jar to assign the Region is shared via [1] as well. The HBCK2 Command has other Options, which (If performed without any oversight) may cause issues with HBase Table availability. The "Master Is Initializing" Error Fix as shared via [1] shouldn't cause any Table to be in Broken State & without knowing the explicit details into the Broken State, It's harder to confirm if Delete-Recreate was the ONLY Way Or, We could have restored the Table in other ways. Having said that, the Post covers "Master Is Initializing" Error & the same has been addressed. As such, We shall mark the Post as Closed. Feel free to share your observation with the Tables in Broken State in a New Post, if you wish to engage for the Community observation & feedback.

Greetings @yagoaparecidoti Thanks for using Cloudera Community. Based on the Post, you wish to confirm if the "maxClientCnxns" Parameter set via CDM (Assuming you mean CM) for ZooKeeper Service is referred in any file associated. You may refer to the Value of "maxClientCnxns" in "zoo.cfg" file associated with the ZooKeeper Process. In CDP/CDH (Managed by CM), You may refer to the same within the ZooKeeper Process Directory under "/var/run/cloudera-scm-agent/process/<ZooKeeper-Process-Directory>/zoo.cfg". The concerned file would be referred in the "ps" Output of the ZooKeeper Process as well. Regards, Smarak

Hello @Neil_1992 & @maykiwogno While we wait for our Nifi Guru @MattWho review, Wish to provide a bit of information on the Lucene Exception. It appears Nifi Provenance Repository uses Lucene for indexing & the AlreadyClosedException means the Lucene Core being accessed has been Closed already, owing to FileSystemException with "Too Many Open Files" for the one of the Core Content "/provenance_repo/provenance_repository/lucene-8-index-1647749380623/_vd_Lucene80_0.dvd". Once AlreadyClosedException is reported, Restarting the Lucene Service would ensure the Cores are initialized afresh. Wish to check if your Team have attempted to increase the OpenFileLimit of the User running the Nifi Process to manage the FileSystemException with "Too Many Open Files" & restart Nifi, which I assume would restart the Lucene Cores as well. Note that the above answer is provided from Lucene perspective as I am not a Nifi Expert. My only intention to get your team unblocked, if the issue is preventing any Nifi concerns. Regards, Smarak
