今天的博客介绍大数据安全系列之spark的kerberos配置

一、spark安装

1、解压和重命名安装目录

 364  tar -zxvf spark-2.4.0-bin-hadoop2.7.tgz -C /usr/local/
  365  cd /usr/local/
  366  ll
  367  mv spark-2.4.0-bin-hadoop2.7/ spark

　　

2、设置spark的环境变量

export SPARK_HOME=/usr/local/spark
export PATH=$PATH:$SCALA_HOME/bin:$SPARK_HOME/bin

　　

3、修改spark的env文件

[root@cluster2-host1 conf]# vim spark-env.sh

　　

export JAVA_HOME=/usr/local/java   #Java环境变量
export SCALA_HOME=/usr/local/scala #SCALA环境变量
export SPARK_WORKING_MEMORY=1g  #每一个worker节点上可用的最大内存
export SPARK_MASTER_IP=cluster1-host1   #驱动器节点IP
export HADOOP_HOME=/usr/local/hadoop  #Hadoop路径
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop #Hadoop配置目录

　　

4、修改spark的conf文件

[root@cluster2-host1 conf]# cp spark-defaults.conf.template spark-defaults.conf
[root@cluster2-host1 conf]# pwd
/usr/local/spark/conf

　　

spark.yarn.jars=hdfs://cluster1-host1:9000/spark_jars/*

　　

5、修改slaver文件

[root@cluster2-host1 conf]# cp slaves.template slaves
cluster2-host2
cluster2-host3

　　

6、创建spark在hdfs上的jar包路径

[root@cluster2-host1 conf]# hadoop fs -mkdir /spark_jars
[root@cluster2-host1 conf]# hadoop dfs -ls /
DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.

Found 1 items
drwxr-xr-x   - root supergroup          0 2020-03-02 04:30 /spark_jars

　　

7、分发安装包到其它节点

8、启动spark

Cd /usr/local/spark/sbin
[root@cluster2-host1 sbin]# ./start-all.sh

　　

检查进程

[root@cluster2-host1 sbin]# jps
25922 ResourceManager
31875 Master
6101 Jps
26152 NodeManager
22924 NameNode
23182 DataNode

　　

[root@cluster2-host2 conf]# jps
22595 SecondaryNameNode
29043 Jps
22268 DataNode
24462 NodeManager
27662 Worker

　　

[root@cluster2-host3 ~]# jps
25025 NodeManager
28404 Worker
12537 Jps
22910 DataNode
[root@cluster2-host3 ~]#

　　

9、浏览器访问页面

http://10.87.18.34:8080/

　　

二、配置spark的kerberos配置

spark的kerberos不需要配置，只需要保证hdfs的kerberos配置正确即可

保证使用hdfs的用户已经验证，且本地有缓存，或者指定keytab文件也可以

[root@cluster2-host1 bin]# klist
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: hdfs/cluster2-host1@HADOOP.COM

Valid starting       Expires              Service principal
03/03/2020 08:06:49  03/04/2020 08:06:49  krbtgt/HADOOP.COM@HADOOP.COM
	renew until 03/10/2020 09:06:49

　　

进行如下的验证，能访问hdfs的数据即可

./spark-shell

scala> var file = "/input/test.txt"
file: String = /input/test.txt

                                                       ^

scala> spark.read.textFile(file).flatMap(_.split(" ")).collect
res1: Array[String] = Array(adfaljal, fjalfjalf, falfja, lfajsa, 23fdjalfja, abc, dda, haoop, cluster, cluster)
