Subject [jira] [Commented] (HADOOP-12726) Unsupported operations should throw UnsupportedOperationException
Date Thu, 21 Jan 2016 18:29:39 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12726?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15111051#comment-15111051
] 

Steve Loughran commented on HADOOP-12726:
-----------------------------------------

in favour for all FS operations. In an ideal world, you'd even be able to tell in advance
what was unsupported, but as it may depend on the specific FS instance, that's a tough one,
especially for rawfs

> In the {{FileSystem}} implementation classes, unsupported operations throw {{new IOException("Not
supported")}}, which makes it needlessly difficult to distinguish an actual error from an
unsupported operation.  They should instead throw {{new UnsupportedOperationException()}}.
> It's possible that this anti-idiom is used elsewhere in the code base.  This JIRA should
include finding and cleaning up those instances as well.
