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,
Thejas

Hi Thejas,
Thank you very much. It was exactly that. You spare me hours of headache.
I insert all the jars of hadoop, hive, hbase and pig in my classpath. In
hive 0.80, there
is :
ant-contrib-1.0b3.jar
antlr-2.7.7.jar
antlr-3.0.1.jar
antlr-runtime-3.0.1.jar
I just removed all of them. It works also if you remove only the 'antlr*'.
Thanks again,
Étienne
