I never needed the -S. I would just call it with -e, but yeah, that's the basic idea. The output is gathered in the remaining optional arguments to exec().

If I run the same command inside hive (without -e) it still works...but if I exec it with a -e from php (so obviously the apache user), I get "Error in semantic analysis: Unable to fetch table [tablename]". Bear in mind that this overall system worked perfectly for weeks. I haven't modified the code or anything. What did change was I had to reinstall hadoop and hive and I'm sure some configuration parameter is not correct now. I found some Google references to this error but no clear-but solutions.
