Martin Bukatovic updated HADOOP-10723:
--------------------------------------
Labels: hcfs (was: )
> FileSystem deprecated filesystem name warning : Make error message HCFS
> compliant
> ---------------------------------------------------------------------------------
>
> Key: HADOOP-10723
> URL: https://issues.apache.org/jira/browse/HADOOP-10723
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs
> Reporter: jay vyas
> Labels: hcfs
>
> In the {{FileSystem.java}} class we've found that if we have an alternative
> filesystem (i.e. xyz://) and we enter it without slashes, we get an hdfs
> specific error message.
> There are two problems with this.
> 1) This is a conceptual bug because the hadoop-common FileSystem interface
> shouldn't have explicit knowledge/dependencies on any particular
> implementation and
> 2) This results in a misleading error message:
> {{hadoop fs -fs xyz: -mkdir -p /foo/bar}}
> Yields an error message which suggests an hdfs URI.
> {noformat}
> # hadoop fs -fs xyzfs: -mkdir -p /foo/bar
> 14/06/12 17:57:24 WARN fs.FileSystem: "xyz:" is a deprecated filesystem name.
> Use "hdfs://xyz:/" instead.
> {noformat}
> Would be better if the error message threw an Exception (as suggested in the
> comments) and was something that didnt hardcode the hdfs uri to the
> beggining, as its very confusing when running on any alternative filesystem.
