Zeppelin使用spark解释器

Zeppelin为0.5.6

Zeppelin默认自带本地spark，可以不依赖任何集群，下载bin包，解压安装就可以使用。

使用其他的spark集群在yarn模式下。

配置：

vi zeppelin-env.sh

添加：

export SPARK_HOME=/usr/crh/current/spark-client
export SPARK_SUBMIT_OPTIONS="--driver-memory 512M --executor-memory 1G"
export HADOOP_CONF_DIR=/etc/hadoop/conf

Zeppelin Interpreter配置

注意：设置完重启解释器。

Properties的master属性如下：

新建Notebook

Tips：几个月前zeppelin还是0.5.6，现在最新0.6.2，zeppelin 0.5.6写notebook时前面必须加%spark，而0.6.2若什么也不加就默认是scala语言。

zeppelin 0.5.6不加就报如下错：

Connect to 'databank:4300' failed

%spark.sql
select count(*) from tc.gjl_test0

报错：

原因：

进入/opt/zeppelin-0.5.6-incubating-bin-all目录下:

# ls lib |grep jackson
jackson-annotations-2.5.0.jar
jackson-core-2.5.3.jar
jackson-databind-2.5.3.jar

将里面的版本换成如下版本：

# ls lib |grep jackson
jackson-annotations-2.4.4.jar
jackson-core-2.4.4.jar
jackson-databind-2.4.4.jar

测试成功！

Sparksql也可直接通过hive jdbc连接，只需换端口，如下图：
