Hadoop/Spark开发环境配置

Posted 2020-09-05 成平艺君

修改hostname bogon 为localhost

查看ip地址

[training@bogon ~]$ sudo hostname localhost
[training@bogon ~]$ hostname

执行结果

此时python 版本为2.7

将python版本升级至3.0及以上

一、            下载欲升级python版本 Python-3.4.5,将包放于本机与虚似机的共享目录下，上传至虚似机的opt目录下

二、            解压

 

三、阅读README安装步骤，根据实验步骤向下执行

 

执行完成后出现Succssfully，恭喜你！安装成功！

 

四、配置环境变量，让Spark用到新版本的Python。编辑 ~training/.bashrc，添加如下内容，并在相应位置下载ipython3

五、   修改 spark-evn.sh 配置文件中的对应参数PYSPARK_PYTHON，此文件一般在 /etc/spark/conf 或者Spark 安装目录的conf 目录下。

 

六、 Python和ipython都升级完成，但是spark的版本是1.6的，下面我们开始升级spark

此时我们已经将python升级到3.4.5，但是spark的版本没有改变！！

升级spark

一、将共享文件夹中的要升级的spark版本到opt目录下

 

二、解压

[training@localhost opt]$ tar -zvxf spark-2.1.0-bin-hadoop2.6.tgz
[training@localhost conf]$ ls /opt/
spark-2.1.0-bin-hadoop2.6.tgz  spark-2.1.0-bin-hadoop2.6

三、修改新版Spark配置文件，将Hadoop、hive 配置文件拷贝到Spark配置文件目录中：

四、安装成功后的页面

五、虽然下载成功了，但是对于一些日常代码的编写与保存不好，所以我们需要下载一个notebook

运行界面

安装matplotlib 库

 

测试matplotlib 库
