[GitHub] [incubator-dolphinscheduler] zhanguohao opened a new issue #4866: [Bug][Common] Not loaded `hdfs-site.xml` causes the client to fail to access the datanode
zhanguohao opened a new issue #4866:
URL: https://github.com/apache/incubator-dolphinscheduler/issues/4866
**For better global communication, Please describe it in English. If you feel the description in English is not clear, then you can append description in Chinese(just for Mandarin(CN)), thx! **
**Describe the bug**
A clear and concise description of what the bug is.
When the configuration is initialized when accessing hdfs, the Configuraion class is used. This class will only load core-site.xml, which leads to mismatch between the client and server parameters, resulting in access failure. Actually, it should be his child Class HdfsConfiguration, so that hdfs-site.xml can be loaded
在访问hdfs时初始化配置的时候，采用的是Configuraion类，这个类只会加载core-site.xml，由此导致客户端和服务端参数不匹配，导致访问失败，实际应该使用的是他的子类HdfsConfiguration，这样才能加载hdfs-site.xml
