org.apache.spark.api.python.PythonRDD.saveAsNewAPIHadoopFile Error
1
in a new prjoct I would like to use Apache-Spark and elasticSearch i found many tutorial and i found this code that I have adapted:
import os
import json
from pyspark import SparkContext, SparkConf
from pyspark.sql import SQLContext
os.environ['PYSPARK_SUBMIT_ARGS'] = '--jars elasticsearch-spark_2.11-2.4.5.jar pyspark-shell'
sc = SparkContext(appName="AllCountries")
es_write_conf = "es.nodes": 'localhost', "es.port" : '9200', "es.resource" : 'testindex/testdoc', "es.batch.size.entries": 1, "es.input.json" : "yes", "es.mapping.id": "doc_id"
data = [ 'some_key': 'some_value', 'doc_id': 123, 'some_key': 'some_value', 'doc_id': 456, 'some_key': 'some_value', 'doc_id': 789 ]
rdd = sc.parallelize(data)
def format_data(x):
return (data[0]['doc_id'], json.dumps(data))
rdd = rdd.map(lambda x: format_data(x))
rdd.saveAsNewAPIHadoopFile(
path='-',
outputFormatClass="org.elasticsearch.hadoop.mr.EsOutputFormat",
keyClass="org.apache.hadoop.io.NullWritable",
valueClass="org.elasticsearch.hadoop.mr.LinkedMapWritable",
conf=es_write_conf)
But i have this error:

Looks like the error is on the config object. Try setting"es.batch.size.entries": "1"instead

Can you check why is it throwingjava.lang.Integer cannot be cast to java.lang.String?
