Thanks but that requires fixing the table schema. Actually, I haven't found
a way to change the delimiters of an existing table (created with a LIKE
statement). I did find a workaround.
While I don't know the schema of the data, I do know the number of columns,
so I am going to create a table with N string columns and my preferred
delimiter and then insert into it. Hive doesn't seem to mind inserting
numeric data into a string column so that should work regardless of the
expressions I will be "inserting".
