What php, you are using exec('hive -S -e "select * from some_table"')
or something like that in php?

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.
