jay vyas updated HADOOP-10723:
------------------------------
Description:
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.
