PIG to load a Map Type

["Venkatraman, Jagadish" <Ja...@morganstanley.com>]

Hi Pig Users/Dev,

We are using PIG for largescale log analysis of our server logs.
Our log records are of the format,
instance_name, host_name, processing_time, [component1#1,component2#322,component3]

A line in our CSV file looks like,
Instance1,host1.ms.com,323,[component1#22,componentprocessor#33,third_component#299]


We are attempting to load the data as <string,string,int,map[string,int]> type.

A snapshot from our pig script looks like,

A = LOAD 'dlink_data.pig' using PigStorage(',') AS (instance_name:chararray,host_name:chararray,processing_time:int, components_map:map[]);
DUMP A;

The first 3 fields load correctly.  The Map, however, does not get loaded.
Can someone please advise on this?
