Hbase error. org.apache.hadoop.hbase.client.RetriesExhaustedException: Failed after attempts=10, exceptions

I'm working with Hbase and I have started to get an ugly error when I query Hbase.

The problem is when I try to get a connection with Hbase I get this error. The only thing it's that I'm using threads,,, but not too many really. 

Caused by: org.apache.hadoop.hbase.client.RetriesExhaustedException: Failed after attempts=10, exceptions:

I closed the connection some part of the code first time, so next times I tried to get the connection it was closed.

Either your HMaster or region server is not running. Check your logs. Can you use hbase shell to do a list command?
