hdfs rebalncing

[#1]

Hi,

is there anyway to run the balancer automatically everyday.

[#2]

At present there is no inbuilt way to do this.

You can however, regularly schedule a balancer command as a Linux CRON
job, to run daily at a preferred time.
Or, if you use CM, you can trigger its balancer actions via the REST
API documented at
http://cloudera.github.io/cm_api/apidocs/v7/path__clusters_-clusterName-_services_-serviceName-_comm...

[#3]

here is my scenario:

i have three 3 hadoop boxes and i have no replication,

when the data is comming to hdfs tha toatal datat is stored into box1 event htough theres is a space in 2 and 3 boxes.

please help me that is this is the issue causing by replication?

By default the frame work will store the data in round robin mannaer,right?

The default policy of a HDFS client is to store its first block
replica on the same node as the client, if the client host is also
serving a DataNode. This is for optimisation of writes.

If you want a more randomized write, write from outside of the cluster
nodes (i.e. from a host that is not a DataNode).
