Akira AJISAKA commented on HDFS-7116:
-------------------------------------
bq. This seems wrong to show it in metric since it is a mostly constant value.
Just like that we won't show other conf values in metric.
I understand. Thanks [~szetszwo] for the comment.
bq. Now, your approach is avoiding this problem. I'll start preparing a patch
if others agree to this approach.
Agree.
bq. Command options are case insensitive.
{code:title=DFSAdmin.java}
try {
if ("-report".equals(cmd)) {
report(argv, i);
} else if ("-safemode".equals(cmd)) {
setSafeMode(argv, i);
} else if ("-allowSnapshot".equalsIgnoreCase(cmd)) {
allowSnapshot(argv);
...
{code}
dfsadmin command options are case sensitive except allowSnapshot and
disallowSnapshot. I'm thinking we should make them case insensitive in a
separate jira.

> Now reading logs is the only way to check how the balancer bandwidth is set.
> It would be useful for administrators if they can get the value of the same.
> This jira to discuss & implement the way to access the balancer bandwidth
