In order to run a balancer on only one data node hdfs balancer -include -f <#datanode name can be specified> this would balance the data load on that particular DN.

@Jay Kumar SenSharma is there way we can get "Average percentage of local files to Region server in the cluster" for entire HBase cluster instead of querying by each region server , thanks.

You don't really need to turn off the vectorization, just need to clean any date outside of the range specified for vectorization 🙂

@Jalender Can you do distinct on mdse_item_i column alone with and without casting and share me the results? I think some leading spaces sometimes could lead to these issues.

@Geoffrey Shelton Okot Thank you.

@Jalender were you able to find out what was eating your resource manager heap? We are also experiencing the same thing but not daily. and our cluster is very much smaller than yours (only 29 data nodes) and when it is idle, RM heap should more or less be under 30% only. but on some days, we get very high RM heap when cluster is totally idle. also checked "yarn.resourcemanager.state-store.max-completed-applications" and it just means value is less than or equal to "yarn.resourcemanager.max-completed-applications" which is default at 10,000.

@Jalender, Activity explorer password is not stored in plain text format. You can login to the node where Activity explorer is installed. Open the file ( /etc/smartsense-activity/conf/shiro.ini ) and find the password [users] admin = admin ---------> password [main] sessionManager = org.apache.shiro.web.session.mgt.DefaultWebSessionManager securityManager.sessionManager = $sessionManager securityManager.sessionManager.globalSessionTimeout = 86400000 shiro.loginUrl = /api/login [urls] /api/version = anon /** = authc If you want to change the password, Go to Ambari -> SmartSense -> Configs -> Activity Analysis -> Password. Change the password and restart the services Thanks, Aditya

You may use user_permission <table> in the hbase shell for the list of the users that can access to the table. Also you may run scan 'hbase:acl', but that would require superuser privs in HBase.

@Jalender Reddy The Fix is to Have the TEZ as default engine from now on.

Issue resolved by setting below property set tez.grouping.max-size = 268,435,456;
