Execute the below add/update command for single mount entry for single nameservice pointing to multiple destinations.
- hdfs dfsrouteradmin -add /apps1 hacluster /tmp1
- hdfs dfsrouteradmin -add /apps1 hacluster /tmp1,/tmp2,/tmp3
- hdfs dfsrouteradmin -update /apps1 hacluster /tmp1,/tmp2,/tmp3 -order RANDOM
Actual. With the above commands, mount entry is successfully updated.
But order information like HASH, RANDOM is not displayed in mount entries and also not displayed in federation router UI. However order information is updated properly when there are multiple nameservices. This issue is with single nameservice having multiple destinations.
Order information should be updated in mount entries so that the user will come to know which order has been set.
