Re: java.io.NotSerializableException: org.apache.avro.mapred.AvroKey using spark with avro
I did not encounter this with my Avro records using Spark 1.10 (see https://github.com/medale/spark-mail/blob/master/analytics/src/main/scala/com/uebercomputing/analytics/basic/UniqueSenderCounter.scala). I do use the default Java serialization but all the fields in my Avro object are Serializable (no bytes/ByteBuffer). Does your Avro schema use bytes? If so, it seems that is wrapped in ByteBuffer, which is not Serializable. A quick search has a fix here: https://groups.google.com/forum/#!topic/spark-users/6HQPuxsCe0c Hope this helps, Markus On 12/17/2014 08:14 PM, touchdown wrote: Yeah, I have the same problem with 1.1.0, but not 1.0.0. -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/java-io-NotSerializableException-org-apache-avro-mapred-AvroKey-using-spark-with-avro-tp15165p20752.html Sent from the Apache Spark User List mailing list archive at Nabble.com. - To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org - To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
Re: java.io.NotSerializableException: org.apache.avro.mapred.AvroKey using spark with avro
Hi, I had the same problem. One option (starting with Spark 1.2, which is currently in preview) is to use the Avro library for Spark SQL. Other is using Kryo Serialization. by default spark uses Java Serialization, you can specify kryo serialization while creating spark context. val conf = new SparkConf().set(spark.serializer, org.apache.spark.serializer.KryoSerializer) val sc = new SparkContext(conf) This worked for me.

Yeah, I have the same problem with 1.1.0, but not 1.0.0. -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/java-io-NotSerializableException-org-apache-avro-mapred-AvroKey-using-spark-with-avro-tp15165p20752.html Sent from the Apache Spark User List mailing list archive at Nabble.com. - To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
