0001-Fixed-NullPointerException-writing-.pig_header-for-f.patch
Pig throws an NPE writing .pig_header for field with null name. Attached patch
has it instead write field name as '$i' corresponding to the field's zero-based
position -- i.e., if the second field is unnamed, its header will be written as
$1.
