1.hadooptool131

CDH部署hdfs 、yarn、 hbase的gateway⻆⾊(其实目的是为了客户端配置文件)

2.keytab⽂件权限(每个节点)

[root@hadooptool131 ~]# chmod 777 /etc/kerberos/*.keytab

3.Apache Spark配置CDH Hadoop目录

[root@hadooptool131 ~]# vi /opt/software/spark/spark-2.4.0-bin-hadoop2.6/conf/spark-env.sh

HADOOP_CONF_DIR=/etc/hadoop/conf

YARN_CONF_DIR=/etc/hadoop/conf

SPARK_HOME=/opt/software/spark/spark

SPARK_CONF_DIR=${SPARK_HOME}/conf

4.hbase-site.xml做软连接到Hadoop配置目录

[root@hadooptool131 ~]# ln -s /etc/hbase/conf/hbase-site.xml /etc/hadoop/conf/hbase-site.xml

5.配置hdfs⽬录得/user权限

[root@hadooptool131 ~]# kinit hdfs

Password for hdfs@HADOOP.COM:

[root@hadooptool131 ~]# hdfs dfs -chmod -R 777 /user

6.cdh yarn的配置

min.user.id : 0

banned.users : yarn mapred bin

allowed.system.users : nobody impala hive llama hdfs hbase

7.重启yarn服务，⽣效配置

8.提交jar

spark提交到yarn平台，需要principal、keytab参数

[root@hadooptool131 ~]# klist

klist: No credentials cache found (filename: /tmp/krb5cc_0)

自带Pi案例提交

${SPARK_HOME}/bin/spark-submit \
--master yarn \
--deploy-mode cluster \
--queue ruozedata \
--driver-memory 1G \
--num-executors 1 \
--executor-memory 1G \
--executor-cores 1 \
--principal hdfs@HADOOP.COM \
--keytab /etc/kerberos/hdfs.keytab \
--class org.apache.spark.examples.SparkPi \
/root/spark-2.4.2-bin-hadoop2.6/examples/jars/spark-examples_2.12-2.4.2.jar

生产ETL标准提交参数（有兴趣小伙伴可以收藏）
