The tool is similar to Balancer. It periodically scans the files in HDFS to check if the block placement satisfies the storage policy. For the blocks violating the storage policy, it moves the replicas to a different storage type in order to fulfill the storage policy requirement. Note that it always tries to move block replicas within the same node whenever possible. If that is not possible (e.g. when a node doesnât have the target storage type) then it will copy the block replicas to another node over the network. * Command: --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
