Zeppelin throws java.lang.OutOfMemoryError: Java heap space

Question

I am trying to use Zeppelin with the following code:

val dataText = sc.parallelize(IOUtils.toString(new URL("http://XXX.XX.XXX.121:8090/my_data.txt"),Charset.forName("utf8")).split("\n"))


case class Data(id: string, time: long, value1: Double, value2: int, mode: int)
val dat = dataText .map(s => s.split("\t")).filter(s => s(0) != "Header:").map(
    s => Data(s(0), 
            s(1).toLong,
            s(2).toDouble,
            s(3).toInt,
            s(4).toInt
        )
).toDF()
dat.registerTempTable("mydatatable")

this keeps throwing me following error :

I have already set the following in the zeppelin-env.sh

export ZEPPELIN_JAVA_OPTS="-Dhdp.version=2.3.0.0-2557 -Dspark.executor.memory=4g"

any idea what I may be missing. File I am parsing my_data.txt is about 200MB

BTW I am using the Hortonworks Sandbox if that matters

EDIT 1 Here is my zeppelin-env.sh

export HADOOP_CONF_DIR=/etc/hadoop/conf
export ZEPPELIN_PORT=9995
export ZEPPELIN_JAVA_OPTS="-Dhdp.version=2.3.0.0-2557 -Dspark.executor.memory=4g"
export SPARK_SUBMIT_OPTIONS="--driver-java-options -Xmx4g"
export ZEPPELIN_INT_MEM="-Xmx4g"
export SPARK_HOME=/usr/hdp/2.3.0.0-2557/spark

Answer 1

Can you try increasing the memory in SPARK_SUBMIT_OPTIONS in conf/zeppelin-env.sh:

export SPARK_SUBMIT_OPTIONS="--driver-java-options -Xmx20g"
