在齐柏林飞艇上安装CassandraInterpreter

Question

我正在齐柏林飞艇上安装CassandraInterpreter。正如文件中所说的那样，我做到了：

bin/install-interpreter.sh --name cassandra

这使得卡桑德拉文件夹与所有的依赖。我现在有点担心。我使用的是开源卡桑德拉3.10.和齐柏林飞艇版本0.7.0.正如我所看到的，齐柏林飞艇正在下载datastax的卡桑德拉派生器，我不使用Datastaxs。

此外，我还添加了Cassandra作为整数，并编写了我的第一个脚本：

%cassandra
HELP;

一些丑恶的事情发生了：

正如我所看到的，Scala版本中的问题--默认情况下--我指的是2.10.5，齐柏林飞艇也在下载。我试着用2.12.0交换整个scala，我得到了关于显示的错误.也是scala错误。有什么想法吗？

我怀疑Cassandra驱动程序的不匹配，因为我有开源的Cassandra，而且驱动程序是用于Datastax的，而且我也找不到开源的。

Answer 1

因此，为了安装cassandra驱动程序，您需要更改一些位解释器罐子。为此，在您通过齐柏林飞艇( zeppelin )解释器安装cassandra之后，您需要进入您的

ZEPPELIN_HOME/zeppelin-server/interpreter/cassandra

之后，您需要这个libs ->

cassandra-driver-core-3.0.1.jar   netty-common-4.0.33.Final.jar            
scalate-core_2.11-1.7.1.jar      commons-lang3-3.3.2.jar          
netty-handler-4.0.33.Final.jar    scalate-util_2.11-1.7.1.jar
guava-16.0.1.jar                 
netty-transport-4.0.33.Final.jar         
scala-xml_2.11-1.0.1.jar
lz4-1.3.0.jar                    
scala-compiler-2.11.2.jar               
slf4j-api-1.7.10.jar
metrics-core-3.1.2.jar          
scala-library-2.11.2.jar                 
snappy-java-1.0.5.4.jar
netty-buffer-4.0.33.Final.jar    
scala-parser-combinators_2.11-1.0.1.jar  
zeppelin-cassandra_2.11-0.7.2.jar
netty-codec-4.0.33.Final.jar     
scala-reflect-2.11.2.jar

在进行此更改后，只需重新启动解释器即可。
