Daniel Dai commented on PIG-4931:
---------------------------------
There are extra spaces, such as "<p>IN (expression) </p>", should be
"<p>IN (expression)</p>", "<p>int </p>" should be "<p>int</p>". Also the last
line of the change "</section></section>" should be "</section>" (otherwise a
compilation error).
I don't understand the type table part. In SUM, the type table tells if the
input is int, SUM output a long type. But for IN, the output is always a
boolean, how's the type table interpreted?
