Hi Ruihong -- if you can coalesce your data into (key1, value1, key2, value2, key3, value3...) format, then you can use the TOMAP built-in function:
https://issues.apache.org/jira/browse/PIG-1809 If you have more complex conversion requirements, then you can pass the data off to a UDF which returns back a map.
