Zeppelin0.5.6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:
