Andrew Hitchcock commented on PIG-1564:
---------------------------------------

Hi all,

I think this patch is still useful. With current Pig trunk you can't CD between 
different filesystems. Example:

grunt> pwd
hdfs://ip-10-218-57-248.ec2.internal:9000/user/hadoop
grunt> cd s3://anhi-test-data/
2010-08-27 23:53:10,522 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 
2999: Unexpected internal error. This file system object 
(hdfs://ip-10-218-57-248.ec2.internal:9000) does not support access to the 
request path 's3://anhi-test-data/' You possibly called FileSystem.get(conf) 
when you should of called FileSystem.get(uri, conf) to obtain a file system 
supporting your path.
Details at logfile: /home/hadoop/pig_1282952081120.log

This patch fixes that issue.

> Currently you can't run Pig scripts that read data from one file system and 
> write it to another. Also, Grunt doesn't support CDing from one directory to 
> another on different file systems.
