Impala EC2 set up instructions no longer working

Hi,

The latest version of Impala doesn't seem to work with the EC2 set up
instructions listed here:

http://blog.cloudera.com/blog/2013/02/from-zero-to-impala-in-minutes

The cluster seems to set up fine, but I get the following error when
running a 'show tables' command from the Hive CLI:

*-bash-4.1$ hive*
*Logging initialized using configuration in
file:/etc/hive/conf.dist/hive-log4j.properties*
*Hive history

*hive> show tables;*

*
*FAILED: Execution Error, return code 1 from

I get the same type of error in the Impala shell.

Can someone take a look and update the instructions?

Thanks,

Dave
