Hallo, When I run a simple pig script to LOAD and STORE avro data, I get:-
java.lang.ClassCastException: org.apache.pig.data.BinSedesTuple cannot be cast to org.apache.avro.generic.IndexedRecord Script: REGISTER /tmp/avro-1.6.0.jar; --REGISTER /tmp/avro-1.5.4.jar --REGISTER /tmp/avro-1.4.1.jar; REGISTER /tmp/piggybank-0.9.1.jar; REGISTER /tmp/json-simple-1.1.jar; REGISTER /tmp/jackson-core-asl-1.8.4.jar; REGISTER /tmp/jackson-mapper-asl-1.8.4.jar; avroData=LOAD '$DATA_INPUTDIR' USING org.apache.pig.piggybank.storage.avro.AvroStorage(); dataSubset = FOREACH avroData GENERATE myField1, myField2; describe dataSubset; ----------------------------------------------- -- shows: -- dataSubset : {myField1: int,myField2: int} ----------------------------------------------- STORE dataSubset INTO '$OUTPUTDIR' USING org.apache.pig.piggybank.storage.avro.AvroStorage(); If I use the 1.5.4 jar I get the same error, but the script works with the 1.4.1 version. If I just write one field, then it works with 1.6.0. I see there's been a related issue fixed here: https://issues.apache.org/jira/browse/PIG-2202 https://issues.apache.org/jira/browse/PIG-2195 Can anyone confirm that this or similar works with avro 1.6.0, and/or point me in the right direction concering where the problem may lie? Many thanks, Andrew
