Kettle与Hadoop（九）提交Spark作业

实验目的：
配置Kettle向Spark集群提交作业。

实验环境：
Spark History Server：
172.16.1.126

Spark Gateway：
172.16.1.124
172.16.1.125
172.16.1.126
172.16.1.127

PDI：
172.16.1.105

Hadoop版本：CDH 6.3.1
Spark版本：2.4.0-cdh6.3.1
PDI版本：8.3

Kettle连接CDH参见“https://wxy0327.blog.csdn.net/article/details/106406702”。配置步骤：
1. 将CDH中Spark的库文件复制到PDI所在主机

-- 在172.16.1.126上执行
cd /opt/cloudera/parcels/CDH-6.3.1-1.cdh6.3.1.p0.1470567/lib/spark
scp -r * 172.16.1.105:/root/spark/

2. 为Kettle配置Spark
以下操作均在172.16.1.105以root用户执行。
（1）备份原始配置文件

cp spark-defaults.conf spark-defaults.conf.bak
cp spark-env.sh spark-env.sh.bak

（2）编辑spark-defaults.conf文件.

vim /root/spark/conf/spark-defaults.conf

内容如下：

spark.yarn.archive=hdfs://manager:8020/user/spark/lib/spark_jars.zip
spark.hadoop.yarn.timeline-service.enabled=false
spark.eventLog.enabled=true
spark.eventLog.dir=hdfs://manager:8020/user/spark/applicationHistory
spark.yarn.historyServer.address=http://node2:18088

（3）编辑spark-env.sh文件

vim /root/spark/conf/spark-env.sh

内容如下：

#!/usr/bin/env bashHADOOP_CONF_DIR=/root/data-integration/plugins/pentaho-big-data-plugin/hadoop-configurations/cdh61
SPARK_HOME=/root/spark

（4）编辑core-site.xml文件

vim /root/data-integration/plugins/pentaho-big-data-plugin/hadoop-configurations/cdh61/core-site.xml

去掉下面这段的注释：

<property><name>net.topology.script.file.name</name><value>/etc/hadoop/conf.cloudera.yarn/topology.py</value>
</property>

提交Spark作业：
1. 修改PDI自带的Spark例子

cp /root/data-integration/samples/jobs/Spark\ Submit/Spark\ submit.kjb /root/big_data/

在Kettle中打开/root/big_data/Spark\ submit.kjb文件，如图1所示。

编辑Spark Submit Sample作业项，如图2所示。

2. 保存行执行作业

日志如下：
