Thanks Bob! That was the problem. I got the latest master. After I tried the 0.5.0 snapshot, the error went away.

Never did figure out why the version I built didn't work. sc.version did report 1.4.1. Were you compiling against the 0.5.1-SNAPSHOT source? I got the error against a pre-snapshot "current version at the time" from the master, downloaded about a 1-2 weeks before the snapshot dropped.

Any ideas how to solve it? It worked fine in spark 1.3.0. Only happening after I upgrade to spark 1.4.1. thanks!

Built with no issues for Spark 1.4.1 using "mvn clean install -Pspark-1.4 -DskipTests" or "mvn clean install -Pspark-1.4 -DskipTests -Dhadoop.version=2.6.0 -Phadoop-2.6". Running the default configuration. It seems to be set up to use the right version, just typing, running "sc" returns an object reference or "sc.version" returns 1.4.1. Running the bank example in the sample notebook returns (first line of a long stack dump): com.fasterxml.jackson.databind.JsonMappingException: Could not find creator property with name 'id' (in class org.apache.spark.rdd.RDDOperationScope) at [Source: {"id":"0","name":"parallelize"}; line: 1, column: 1]... ...first Spark-related frame: at org.apache.spark.rdd.RDDOperationScope$.fromJson(RDDOperationScope.scala:82) The bank code executes fine in the Spark Scala shell. In fact, anything that uses Spark past the "sc" command, such as: val data = Array(1, 2, 3, 4, 5) val distData = sc.parallelize(data) Produces the exact same mapping error. So I'm guessing it might be in the rendering. Tried using Firefox on Centos, Firefox on Windows, even IE on Windows. Same error. Does Zeppelin support Spark 1.4? It seems to imply this in the readme. Or is there something else I'm missing? Thanks, Bob
