問題描述：
1.文件無法寫入hadoop hdfs文件系統；
2.hadoop namenode日志記錄
the directory item limit is exceed: limit=1048576
3.hadoop單個目錄下文件超1048576個，默認limit限制數為1048576，所以要調大limit限制數
解決辦法：
hdfs-site.xml配置文件添加配置參數 <property> <name>dfs.namenode.fs-limits.max-directory-items</name> <value>3200000</value> <description>Defines the maximum number of items that a directory may contain. Cannot set the property to a value less than 1 or more than 6400000.</description> </property> 將配置文件推送至hadoop集群所有節點 重啟hadoop服務
