Subject [jira] [Commented] (HDFS-6264) Provide FileSystem#create() variant which throws exception if parent directory doesn't exist
Date Fri, 25 Sep 2015 14:15:05 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6264?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14908074#comment-14908074

Kihwal Lee commented on HDFS-6264:
----------------------------------

It looks like there are places where {{@SuppressWarnings("deprecation")}} is specified.
A quick scan result include 
{noformat}
WebHdfsFileSystem
TestHarFileSystem
TestFileCreation
NativeAzureFileSystem
NativeAzureFileSystemBaseTest
{noformat}

If they are there for {{createNonRecursive()}}, please remove them in the patch.

> Provide FileSystem#create() variant which throws exception if parent directory doesn't
exist

> FileSystem#createNonRecursive() is deprecated.
> However, there is no DistributedFileSystem#create() implementation which throws exception
if parent directory doesn't exist.
> This limits clients' migration away from the deprecated method.
> For HBase, IO fencing relies on the behavior of FileSystem#createNonRecursive().
> Variant of create() method should be added which throws exception if parent directory
doesn't exist.
