Soumyapn created HDFS-13843:
-------------------------------
Summary: RBF: When we add/update mount entry to multiple
destinations, unable to see the order information in mount entry points and in
federation router UI
Key: HDFS-13843
URL: https://issues.apache.org/jira/browse/HDFS-13843
Project: Hadoop HDFS
Issue Type: Bug
Components: federation
Reporter: Soumyapn
*Scenario:*
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.
*Expected:*
*Order information should be updated in mount entries so that the user will
come to know which order has been set.*
