Hi,
Commands : ./hdfs dfsrouteradmin -add /apps ns1 /tmp1 ( /apps pointing to
/tmp1 destination path)
Now i will add one more destination path (/tmp2) using the command
./hdfs dfsrouteradmin -add /apps ns1 /tmp2 (here by default its taking the
order as HASH)
Now if i update the above mount entry using the command
./hdfs dfsrouteradmin -update /apps ns1 /tmp1,/tmp2 -order RANDOM (And if i
try to add any files to the mount entry /apps its giving errors).
