hadoop - MLCP导入java.lang.UnsatisfiedLinkError

我正在尝试使用MLCP将数据导入Marklogic服务器。数据采用XML格式，并位于一个archive(zip)文件中。
MLCP以 java.lang.UnsatisfiedLinkError 结尾
我已经尝试过MLCP 8.0.6和MLCP 8.0.7，但两种情况下的错误相同

详细信息:

Marklogic服务器8.0-6.3

MLCP 8.0.6和MLCP 8.0.7

mlcp.bat -options_file“选项文件路径”

选项文件

import

-host
localhost

-port
8907

-mode
local

-database
dj_test

-username
admin

-password
admin

-input_file_path
"C:\Users\djoshi16\Documents\training-project-data\"

-input_compressed
true

-input_file_type
archive

-thread_count
4

最佳答案

感谢mattsun提供了宝贵的参考。

就我而言，实际问题是类(class)信息冲突。从MLCP的bin目录中删除.dll文件后，所有内容都像一个 super 按钮一样工作。
dll和jars都被运送到MLCP软件包中，这就是为什么很难确定实际问题的原因。
