Hello all,
I'm encountering an error when I call illustrate - it blows up with a null
pointer and the following exception:

java.lang.NullPointerException

org.apache.pig.pen.util.DisplayExamples.ShortenField(DisplayExamples.java:205)

    at org.apache.pig.Main.main(Main.java:321)

This happens with even a 2 step load then illustrate sequence like this:

grunt> data = load '/Users/jkk/projects/weblogdumps/weblogs_2005_11' using
PigStorage('\t') AS (session_id, user_id, page_name, date, params,
total_time, render_time, db_time, ip, cookies, user_agent, referrer, ajax,
http_verb);
grunt> illustrate data;
This trace is from an older pig, but I get a very similar stack dump from
pig 0.5 where the error also occurs.

Is anyone else seeing this? I didn't get a lot of hits in google.

thanks!
james
