This is not an error and you shouldn't be worried. It is rather a noisy INFO log that should be fixed (as a DEBUG level instead) in subsequent releases (Are you using CDH3 or CDH4? IIRC only CDH3u3 printed these, not in anything above that.) > 2. Another Aspect is when I start the hbase master it closes automatically > after a while.
