@ram sriram The below command sets your replication factor to 1 for all new files you will create, with a potential data loss unless you are running HDP 3.x which has a new HDFS algorithm EC erasure coding $ hdfs dfs -setrep -w 1 -R / As responded above the changes only affect new files you will create. After changing the replication factor you won't see any hdfs size changes until the trash time interval which was set on 360 minutes configured by the hdfs trash interval has been reached fs.trash.interval Once the NameNode metadata has been updated, it is the DataNodes which would actually do the operation. There could be some delay, but space is definitely reclaimed. HTH ... View more

@Al Kirmer Unfortunately its a hard and fast rule when it comes to paid support. HWX won't take responsibility or guarantee good functionality of your cluster or it's components.

Usually the all the databases are co-hosted on the same node for hive, oozie, Ambari etc mysql -uroot -p{root_password} create database rangerkms; create user 'rangerkms'@'localhost' identified by '{rangerkms_password}'; grant all privileges on rangerkms.* to 'rangerkms'@'localhost'; grant all privileges on rangerkms.* to 'rangerkms'@'%'; grant all privileges on rangerkms.* to 'rangerkms'@'{DB_HOST}' identified by '{rangerkms_password}'; grant all privileges on rangerkms.* to 'rangerkms'@'{DB_HOST}' with grant option; grant all privileges on rangerkms.* to 'rangerkms'@'%' with grant option; flush privileges; quit; After the above statements have run successfully use the above user/password to reconfigure your rangerkms it should start up HTH ...
