Dmitriy V. Ryaboy commented on PIG-2562:
----------------------------------------
According to the hortonworks blog post, 10 should work with EMR. Can you verify
that the 0.10 release still has this problem, and post instructions to
reproduce?

> According to this thread, only Amazon's proprietary hadoop-core.jar enables
> S3 to work on with Pig. Apache Pig does not work.
> Example:
> Apache Pig branch-0.9 as of today:
> hadoop@ip-10-195-159-114:~$ pig/bin/pig
> grunt> cd s3://elasticmapreduce/samples/pig-apache/input/
> 2012-02-29 05:45:22,282 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR
> 2999: Unexpected internal error. This file system object
> (hdfs://10.195.159.114:9000) does not support access to the request path
> 's3://elasticmapreduce/samples/pig-apache/input' You possibly called
> FileSystem.get(conf) when you should have called FileSystem.get(uri, conf) to
> obtain a file system supporting your path.
