Errors

[Josh Ferguson]

So say I'm using some ruby code to shell out to hive for data loading  
such as:

hive -e "LOAD ..."
What's the preferred method of detecting errors in this situation? Do  
the failures return some sort of error codes that I could normally  
catch or am I stuck doing parsing of the results? Also, is there a  
preferred method for doing this straight in java?
