时间 2021-01-21

问题#1：

GetTaskAttemptCompletionEventsRequestPBImpl.java 解压失败
-------------------------------------------------------------

!   F:\解包测试\hadoop-2.7.3-src.rar: 无法创建
hadoop-2.7.3-src\hadoop-mapreduce-project\hadoop-mapreduce-client\hadoop-mapreduce-client-common\src\main\java\org\apache\hadoop\mapreduce\v2\api\protocolrecords\impl\pb\GetTaskAttemptCompletionEventsRequestPBImpl.java
    路径和文件名总长度必须不能超过 260 个字符
    系统找不到指定的路径。
!   F:\解包测试\hadoop-2.7.3-src.rar: 没有文件被解压

分析：

解压成功文件 FailTaskAttemptRequestPBImpl.java 所在的目录
-----------------------------------------------------

C:\Users\lsq\AppData\Local\Temp\Rar$DR44.648\hadoop-2.7.3-src\hadoop-mapreduce-project\hadoop-mapreduce-client\hadoop-mapreduce-client-common\src\main\java\org\apache\hadoop\mapreduce\v2\api\protocolrecords\impl\pb\FailTaskAttemptRequestPBImpl.java

确定解压的临时目录的起点
-----------------------------------------------------

C:\Users\lsq\AppData\Local\Temp\Rar$DR44.648\

解压失败文件 GetTaskAttemptCompletionEventsRequestPBImpl.java 的临时路径总长度
----------------------------------
C:\Users\lsq\AppData\Local\Temp\Rar$DR44.648\hadoop-2.7.3-src\hadoop-mapreduce-project\hadoop-mapreduce-client\hadoop-mapreduce-client-common\src\main\java\org\apache\hadoop\mapreduce\v2\api\protocolrecords\impl\pb\GetTaskAttemptCompletionEventsRequestPBImpl.java

总长度为264个字符！
超过了winrar设定的260个字符数上限！

解决办法#1：

-----------------
   更改 winrar 设置 -> 临时文件解压的文件夹
       old : C:\Users\lsq\AppData\Local\Temp\
       new1 : F:\forUnzip
