[jira] [Updated] (HADOOP-10723) FileSystem deprecated filesystem
name warning : Make error message HCFS compliant
[ 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:
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 specific error
{{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.
