你好史少峰，我所做的具体步骤是这样的。 1：下载一份kylin2.5.2的源代码。 2：将KYLIN_HOME/tool 文件夹下的jar包复制一份出来。 3：找到报错的类并在其中打上log，编译并替换源文件。 4：重启kylin并再次执行构建。 5：查看log日志，但是我发现一个奇怪的事情，我的KYLIN_CONF即便是配置了。他仍然读不到，我是在kylin.sh中 使用-DKYLIN_CONF来配置的，但是日志打印出来的结果却是另一个路径，所以我现在想确认，这个KYLIN_CONF的作用是？我应该在哪里配置，并且好像我的conf文件夹下的配置文件都被程序读不到。如果需要日志，我可以重现并发送日志。
