3.日誌分析
關鍵是這一句：java.io.FileNotFoundException: File does not exist: hdfs://mycluster/spark_historylog
意思是：找不到指定文件
4.解決方案
需要預先創建文件即可：
hadoop dfs -mkdir hdfs://mycluster/spark_historylog
5.效果展示
[root@hadoop101 conf]# spark-shell
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).
