[jira] Commented: (HADOOP-4034) Redundant deprecation warnings in hadoop logs

["Doug Cutting (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-4034?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12628469#action_12628469 ] 

Doug Cutting commented on HADOOP-4034:
--------------------------------------

> while FileSystem.getFileSysName(URI) returns the file system name without the hdfs:// scheme part

FileSystem#getName() is deprecated.  We should remove calls to it rather than change it.

> Warnings in the form of 
> "org.apache.hadoop.fs.FileSystem - "localhost:57367" is a deprecated filesystem name. Use "hdfs://localhost:57367/" instead."
> are frequently emitted into the hadoop log. The problem is that the frequency of these warnings floods the logs and makes it difficult to discover real issues.
> A short investigation reveals that while FileSystem.getFileSysName(URI) returns the file system name without the hdfs:// scheme part, the method FileSystem.fixName(String) complains about it and appends the hdfs:// back.
