HDFS with JBOD configuration

2014-04-03 Thread Bharath Kumar 
Hi All,
 I have a query with respect to JBOD configuration . Suppose in my
data node if one of the
disk crashes in JBOD configuration will the entire data node be shown as
dead/unavailable ?

AFAIK, data node will be dead since it cannot handle one disk failure ( if
it cannot write data to a disk, it will fail).
But not sure if this situation has changed.
