Local class incompatible?
Hi, I have a test-running zeppelin connected to my spark cluster and cluster setup like this:
Spark: spark-1.4.1-bin-hadoop2.6
Hadoop: hadoop-2.7.1
Zeppelin installed as: mvn clean install -Pspark-1.4 -Dhadoop.version=2.6.0 -Phadoop-2.6 -DskipTests
and ran a test code like this:
val textFile = sc.textFile("hdfs://analytics-master:9000/user/kanizsa.lab/gutenberg")
print textFile.count()
val textFile = sc.textFile("README.md")
print textFile.count()
this code works well with scala interpreter but I'd encountered error when executing similar code as %pyspark.
I'd also ran a code in pyspark command line shell but I works like a charm. no error like below:
How to resolve this error? It seems something inside of zeppelin not compatible with my spark cluster...

Posted by moon soo Lee <mo...@apache.org>.
Hi,
Could you try build Zeppelin with -Dspark.version=1.4.1 ?
mvn clean install -Pspark-1.4 -Dspark.version=1.4.1 -Ppyspark
-Dhadoop.version=2.6.0
-Phadoop-2.6 -DskipTests
Thanks,
moon

Re: Local class incompatible?
Posted by Albert Yoon <yo...@kanizsalab.com>.
Hi,
Although SPARK_HOME correctly set and build Z with -Dpyspark I still experience local class not compatible error when I running any pyspark in Z. Job was correctly send and processed on cluster but the error seems thrown after final stage (Python RDD deserialization?) I followed instruction from Jongyul Lee but it still not effective at all. Any workarounds?

제목: Re: Local class incompatible?
Hi,
I'd build Z with pyspark as like below after fresh git clone:
mvn clean install -Pspark-1.4 -Ppyspark -Dhadoop.version=2.6.0 -Phadoop-2.6 -DskipTests
mvn clean install -Pspark-1.4 -Ppyspark -Dhadoop.version=2.7.0 -Phadoop-2.6 -DskipTests
and then setup environment values
master spark://analytics-master:7077
spark.home /home/kanizsa.lab/spark/spark-1.4.1-bin-hadoop2.6
but all attempts give me the same error when using pyspark:
Py4JJavaError: An error occurred while calling z:org.apache.spark.api.python.PythonRDD.collectAndServe.
