Re: Issue with PigServer: java.lang.NoSuchFieldError: name

Do you have another version of antlr jar in your classpath (different 
from version used in pig)? I have seen this problem earlier, and it 
seemed to go away when I removed unnecessary jars from classpath 
(including antlr).

Thanks,

Hi all,
I try to use pigserver for the first time, I have an exception
and I did not find much about it on the official website and google.

I have a problem to launch a query from a Java program.
The query is tested and works in command line mode.


The java code:

try {
             if(distributed){
                 pig = new PigServer(ExecType.MAPREDUCE);
             }else{
                 pig = new PigServer(ExecType.LOCAL);
             }
             logger.debug("Pig query to launch: \n"+query);
             pig.registerQuery(query);
             logger.debug("Store process...");
             pig.store("A",
"hbase://"+tableNameTo,"org.apache.pig.backend.hadoop.hbase.HBaseStorage('"+hbaseFeat+"')");

         } catch (ExecException e) {....

The logs when tested in local mode:
.
.
[May 31 15:15:04] DEBUG (HBaseStatement.java:407) - Pig query to launch:
