Yes, it is, and it was fine with a single-node cluster.

Dear users,

My pig 0.3.0 and hadoop-0.18.3 worked fine with single node cluster, but
after I change to a 2 - nodes cluster, I got this error as I ran pig:

*org.apache.hadoop.ipc.RPC$VersionMismatch: Protocol
org.apache.hadoop.mapred.JobSubmissionProtocol version mismatch. (client =
11, server = 10)*

Among my environment variables: PIG_HADOOP_VERSION=18

Did I miss any thing? Thank you in advance.

George

do you sure the hadoop run in cluster is hadoop-0.18.3
