-----------------------------------
Summary: RBF: Exit status of dfsrouteradmin -rm should be non-zero
for unsuccessful attempt
Key: HDFS-16957
URL: https://issues.apache.org/jira/browse/HDFS-16957
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Viraj Jasani
Assignee: Viraj Jasani
DFS router admin returns non-zero status code for unsuccessful attempt to add
or update mount point. However, same is not the case with removal of mount
point.
For instance,
{code:java}
bin/hdfs dfsrouteradmin -add /data4 ns1 /data4
..
..
Cannot add destination at ns1 /data4
echo $?
255 {code}
{code:java}
/hadoop/bin/hdfs dfsrouteradmin -rm /data4
..
..
Cannot remove mount point /data4
echo $?
0{code}
Removal of mount point should stay consistent with other options and return
non-zero (unsuccessful) status code.
