Subject [jira] [Commented] (HDFS-5081) DistributedFileSystem#listStatus() throws FileNotFoundException when directory doesn't exist
Date Fri, 09 Aug 2013 17:08:48 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5081?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13734998#comment-13734998
] 

Devaraj Das commented on HDFS-5081:
-----------------------------------

Ted, isn't this a known fact with HADOOP-2.x. I thought we already have code in HBase that
handles this fact. Am I missing something?

> TestMetaMigrationConvertToPB.tgz was generated from filesystem image produced by previous
release of HBase.

release of HBase.
> The test is at hbase-server/src/test/java/org/apache/hadoop/hbase/catalog/TestMetaMigrationConvertingToPB.java
under HBase trunk.
