Hi, I just subscribed to the dev mailing list in order to give you some feedback on pig 0.11 candidate 2.
The following three issues are currently present in 0.11 candidate 2: https://issues.apache.org/jira/browse/PIG-3144 - 'Erroneous map entry alias resolution leading to "Duplicate schema alias" errors' https://issues.apache.org/jira/browse/PIG-3194 - Changes to ObjectSerializer.java break compatibility with Hadoop 0.20.2 https://issues.apache.org/jira/browse/PIG-3195 - Race Condition in PhysicalOperator leads to ExecException "Error while trying to get next result in POStream" The last two of these are easily solveable (see the tickets for details on that). The first one is a bit trickier I think, but at least there is a workaround for it (pass Map fields through an UDF) In my personal opinion, each of these problems is pretty severe, but opinions about the importance of the MAP Datatype and STREAM Operator, as well as Hadoop 0.20.2 compatibility might differ. so far ..
