[jira] [Commented] (HADOOP-16277) Expose getTokenKind method in FileSystem

    [ https://issues.apache.org/jira/browse/HADOOP-16277?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16826428#comment-16826428 ] 

Wei-Chiu Chuang commented on HADOOP-16277:
------------------------------------------

Let's step back a little: what's the purpose of knowing the file system for? why do you think getTokenKind() is a good representation of file system?

> It would be nice to have a getTokenKind() method exposed in [FileSystem|[https://github.com/apache/hadoop-common/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/FileSystem.java]] . Currently WebHdfsFileSystem class has getTokenKind() which is protected. Having it in FileSystem makes it easier to use at runtime when the consumer doesn't know what the underlying FileSystem implementation is.
