Subject [jira] [Resolved] (HADOOP-1303) copyToLocal cast exception for S3 filesystem
Date Fri, 30 Dec 2011 08:01:32 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-1303?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Harsh J resolved HADOOP-1303.
-----------------------------

       Resolution: Not A Problem
    Fix Version/s: 0.23.0

Not a problem anymore. We get appropriate FSes to work with, and do not cast.

> The copyToLocal method in FsShell.java class does the following casting:
> ((DistributedFileSystem)fs).copyToLocalFile(srcs[i], dst, copyCrc);
> which in the case of S3 filesystem, this returns ClassCastException. This can be fixed
by replacing the above line by:
>  fs.copyToLocalFile(srcs[i], dst);
> Which of course does not check for the CRC.
