Mongodb-Hadoop適配器

Question

為了開始使用mongodb-hadoop適配器，我指的是手冊

我的系統上運行的當前hadoop版本是0.20.2。

所以我將build.sbt文件編輯為

hadoopRelease在ThisBuild中：=“ 0.20.2”。

但是，當我嘗試“ sbt軟件包”的下一個命令時，出現以下錯誤。

[error] Hadoop Release '%s' is an invalid/unsupported release.  Valid entries are in 0.20.2
[error] Use 'last' for the full log.

完整的日志是

Answer 1

嘗試更換

hadoopRelease在ThisBuild中：=“ 0.20.2”。

與

hadoopRelease在ThisBuild中：=“ 0.20”。

對我來說，當我將1.0.4設為1.0時，它起作用了。 盡管我不得不承認我沒有檢查穿梭罐子是否工作。

編輯：Jar無法正常工作。 抱怨一些失蹤的班級。
