Getting Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/phoenix/jdbc/PhoenixDriver Exception
Hello folks..,
i am trying to run sample phoenix spark application, while i am trying to
run i am getting following exception:
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/phoenix/jdbc/PhoenixDriver
Here is my sample code:
package com.inndata.spark.sparkphoenix;
import org.apache.spark.SparkConf;
import org.apache.spark.SparkContext;
import org.apache.spark.api.java.JavaSparkContext;
import org.apache.spark.sql.DataFrame;
import org.apache.spark.sql.SQLContext;
import com.google.common.collect.ImmutableMap;
import java.io.Serializable;
/**
*
*/
public class SparkConnection implements Serializable {
public static void main(String args[]) {
SparkConf sparkConf = new SparkConf();
sparkConf.setAppName("spark-phoenix-df");
sparkConf.setMaster("local[*]");
JavaSparkContext sc = new JavaSparkContext(sparkConf);
SQLContext sqlContext = new org.apache.spark.sql.SQLContext(sc);
/*DataFrame df = sqlContext.read()
.format("org.apache.phoenix.spark")
.option("table", "TABLE1")
.option("zkUrl", "localhost:2181")
.load();
df.count();*/
DataFrame fromPhx = sqlContext.read().format("jdbc")
.options(ImmutableMap.of("driver", "org.apache.phoenix.jdbc.PhoenixDriver",
"url",
"jdbc:phoenix:ZK_QUORUM:2181:/hbase-secure", "dbtable", "TABLE1"))
.load();
fromPhx.show();
}
}
I have included phoenix-spark jar to the spark library and as well as
spark-submit command. and i also added *spark.executor.extraClassPath
and **spark.driver.extraClassPath
in spark-env.sh*

Hi,
I think you need to include phoenix-client jar, instead of
phoenix-spark.jar. :-)
