Amar Kamat commented on HADOOP-3251:
------------------------------------
It seems that {{FileSystem#getName()}} is the cause of the problem.
{{FileSystem#getName()}} is a deprecated api and should ideally call
{{FileSystem#getUri().toString()}} which is not the case. There are two ways to
overcome this :
1) Replace all the occurrences of {{FileSystem.getName()}} with
{{FileSystem.getUri().toString()}} OR
2) Fix the deprecated {{FileSystem.getName()}} api to call
{{getUri().toString()}}.
(1) will result into a big patch while (2) will be a small one.
I think we should to go for (2) since this is a blocker for 0.17, comments?

> Issue Type: Bug
> Components: mapred

> Reporter: Mukund Madhugiri
> Assignee: Devaraj Das
> Priority: Blocker

> When a cluster is allocated thru HoD, dfs commands throw a WARN message on
> the command line. This does not affect the cluster functionality, but is bad
> user experience. Hence, marking this a blocker for 0.17.0
> The message is:
> 08/04/14 20:53:46 WARN fs.FileSystem: "namenode:59440" is a deprecated
> filesystem name. Use "hdfs://namenode:59440/" instead.
> The entries in HoD generated hadoop-site.xml should be changed to use
> *hdfs://namenode*, instead of just *namenode*
