修改hostname bogon 為localhost
查看ip地址
[training@bogon ~]$ sudo hostname localhost
[training@bogon ~]$ hostname
執行結果
此時python 版本為2.7
將python版本升級至3.0及以上
一、 下載欲升級python版本 Python-3.4.5,將包放於本機與虛似機的共享目錄下，上傳至虛似機的opt目錄下
二、 解壓
三、閱讀README安裝步驟，根據實驗步驟向下執行
執行完成后出現Succssfully，恭喜你！安裝成功！
四、配置環境變量，讓Spark用到新版本的Python。編輯 ~training/.bashrc，添加如下內容，並在相應位置下載ipython3
五、 修改 spark-evn.sh 配置文件中的對應參數PYSPARK_PYTHON，此文件一般在 /etc/spark/conf 或者Spark 安裝目錄的conf 目錄下。
六、 Python和ipython都升級完成，但是spark的版本是1.6的，下面我們開始升級spark
此時我們已經將python升級到3.4.5，但是spark的版本沒有改變！！
升級spark
一、將共享文件夾中的要升級的spark版本到opt目錄下
二、解壓
[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，將Hadoop、hive 配置文件拷貝到Spark配置文件目錄中：
四、安裝成功后的頁面
五、雖然下載成功了，但是對於一些日常代碼的編寫與保存不好，所以我們需要下載一個notebook
