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).
