You can get your live RegionServer IDs with startcodes included via the HBase Shell command: status 'simple' An output line from this, such as the below: host.cloudera.com:60020 1455726247381 Can then be converted into the right format: host.cloudera.com,22101,1455726247381

I found out why this was happening. Since I was on a DEV cluster I stopped and started the services every day. Also, the data from the table to which I was writing was moving to a single machine from time to time (due to service failing, start and stop etc.) After I balanced the HBase Table the script was distributed.

> Most of them, I do not found them in CM even with the good prefixes (in their corresponding service). Thing to note, Cloudera Manager team will update the configuration to match what is supported in CDH (HDFS, HBASE etc). If a parameter is not exposed in your CM it may be that your CM is dated or that property is not yet avalable/supported for the respective service. For example "dfs.namenode.avoid.read.stale.datanode" is exposed in CM 5.5.1 but not in CM 5.3.x

I found a partial answer to my question: http://hadoop-hbase.blogspot.fr/2013/07/hbase-and-data-locality.html Since I am in DEV, I start and Stop the machines every day. Also, we do restart the service from time to time.

Thank you for pointing this out as I am also seeing the issue in iOS 9's browser. I was able to read the page by rotating the phone to a portrait display which allowed more horizontal space to render the left rail. Hopefully this will give you a temporary work around as I report this to the web team.

I didn't found any OutOfMemory error in the indicated logs (I did a grep). However, changing the heap helped. So it really was a heap problem 🙂 Thank you! Alina

Hello, My fault. I had a timestamp problem. Since in France the hour changed (to UTC+1), and we are having the servers still on UTC+2, I tought that it is not changing. Thank you!

Your understanding seems right, but note that none of the 'splitting' is automatic. At its simplest form, federation is a way to have multiple distinct NameNodes powered by a common set of DataNodes. Effectively, its running and managing 2 or more *separate* namespaces on top of the same storage space. If you deploy two federated NameNodes, say hdfs://host-nn1/ and hdfs://host-nn2, then they will have nothing in common except the Live DN hostnames they share. A 'hadoop fs -ls' done on each will return absolutely independent results.
