Subject [jira] [Created] (SPARK-2576) slave node throw NoClassDefFoundError $line11.$read$ when executing a Spark QL query on HDFS CSV file
Date Fri, 18 Jul 2014 09:55:04 GMT
Svend created SPARK-2576:
----------------------------

             Summary: slave node throw NoClassDefFoundError $line11.$read$ when executing
a Spark QL query on HDFS CSV file
                 Key: SPARK-2576
                 URL: https://issues.apache.org/jira/browse/SPARK-2576
             Project: Spark
          Issue Type: Bug
          Components: Spark Core, SQL
    Affects Versions: 1.0.1
         Environment: 
One Mesos 0.19 master without zookeeper and 4 mesos slaves. 

JDK 1.7.51 and Scala 2.10.4 on all nodes. 

HDFS from CDH5.0.3

Spark version: I tried both with the pre-built CDH5 spark package available from http://spark.apache.org/downloads.html
and by packaging spark with sbt 0.13.2, JDK 1.7.51 and scala 2.10.4 as explained here http://mesosphere.io/learn/run-spark-on-mesos/

All nodes are running Debian 3.2.51-1 x86_64 GNU/Linux and have 

            Reporter: Svend



Execution of SQL query against HDFS systematically throws a class not found exception on slave
nodes when executing .

(this was originally reported on the user list: http://apache-spark-user-list.1001560.n3.nabble.com/spark1-0-1-spark-sql-error-java-lang-NoClassDefFoundError-Could-not-initialize-class-line11-read-tc10135.html)

Sample code (ran from spark-shell): 

{code}
val sqlContext = new org.apache.spark.sql.SQLContext(sc)

import sqlContext.createSchemaRDD

case class Car(timestamp: Long, objectid: String, isGreen: Boolean)

# I get the same error when pointing to the folder "hdfs://vm28:8020/test/cardata"
val data = sc.textFile("hdfs://vm28:8020/test/cardata/part-00000")

val cars = data.map(_.split(",")).map ( ar => Car(ar(0).toLong, ar(1), ar(2).toBoolean))
cars.registerAsTable("mcars")
val allgreens = sqlContext.sql("SELECT objectid from mcars where isGreen = true")
allgreens.collect.take(10).foreach(println)
{code}

Stack trace on the slave nodes:

Note that running a simple map+reduce job on the same hdfs files with the same installation
works fine: 

{code}
# this works
val data = sc.textFile("hdfs://vm28:8020/test/cardata/")

val lineLengths = data.map(s => s.length)
val totalLength = lineLengths.reduce((a, b) => a + b)
{code}

The hdfs files contain just plain csv files: 

{code}
$ hdfs dfs -tail /test/cardata/part-00000
