Jing Huang commented on PIG-1026:
---------------------------------
Created a customer scenario with this schema and storage hint:
(TestJira1026.java)
final static String STR_SCHEMA = "bcookie:bytes,yuid:bytes,
ip:bytes,query_term:bytes,clickinfo:map(String),demog:map(String),page_params:map(String),viewinfo:collection(f1:map(String))";
final static String STR_STORAGE =
"[bcookie,yuid,ip,query_term];[clickinfo#{pos|sec|slk|targurl|cost|gpos},page_params#{ipc|vtestid|frcode|pagenum|query}];[clickinfo,page_params,demog];[viewinfo]";
Got NullPointExcepiton.
