Hello,
I wonder if you guys can help. I'm running Pig 0.9.1 with Hadoop 0.20.203.0,
and am having the below problem consistently. I have tried various cast
operators, none of which are working, so I must assume I'm making a syntactical
error. I just cant see what it is. Can anyone please help?
grunt> describe temp1;
temp1: {group: chararray,temp: {(a::Env_Company: chararray,a::TradeNPV:
double)}}
grunt> temp2 = foreach temp1 generate group, SUM(a.TradeNPV);
2012-01-19 09:58:19,243 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR
1045:
<line 10, column 38> Could not infer the matching function for
org.apache.pig.builtin.SUM as multiple or none of them fit. Please use an
explicit cast.
Thanks in advance,
Ian Meyers
