Subject [jira] [Updated] (HADOOP-10723) FileSystem deprecated filesystem name warning : Make error message HCFS compliant
Date Thu, 19 Jun 2014 13:22:24 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-10723?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.
