Subject: One datanode is down then write/read starts failing
Content-Type: text/plain; charset="ISO-8859-1"; format=flowed
Content-Transfer-Encoding: 7bit

Hello,


I have hadoop cluster setup of one namenode and two datanodes.
And i continuously write/read/delete through hdfs on namenode through 
hadoop client.

Then i kill one of the datanode, still one is working but writing on 
datanode is getting failed for all write requests.

I want to overcome this scenario because at live traffic scenario any of 
datanode might get down then how do we handle those cases.

Can anybody face this issue or i am doing something wrong in my setup.

Thanx in advance.


Warm Regards,
Satyam
