Hello yagoaparecidoti When you start the tablet servers, kudu needs to read all of the block containers located in that tablet server. Depending on how much data is stored there, is the amount of time it can take to open all the containers.  Several variables are also involved such as disk performance, how busy is the host doing other things, if the disks are shared, etc... If it happens to only one host, chances are this host is either facing some hardware issues or have a lot of data to process, otherwise you only have a lot of block containers to work with.   Please let us know if there are further questions we can clarify for you.

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.    Regards, Smarak   [1] https://github.com/apache/hbase-operator-tools/tree/master/hbase-hbck2#master-startup-cannot-progress-in-holding-pattern-until-region-onlined   ...

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 ... View more
