wangzhihui updated HDFS-17356:
------------------------------
Description:
When enabling RBF federation in HDFS, when the HDFS server and RBFClient
share the same configuration and the HDFS server (NameNode、ZKFC) and RBFClient
are on the same node, the following exception occurs, causing NameNode to fail
to start; The reason is that the NS of the Router service has been added to the
dfs.nameservices list. When NameNode starts, it obtains the NS that the current
node belongs to. However, it is found that there are multiple NS that cannot be
recognized and cannot pass the verification of existing logic, ultimately
resulting in NameNode startup failure. Currently, we can only solve this
problem by isolating the hdfs-site.xml of RouterClient and NameNode. However,
grouping configuration is not conducive to our unified management of cluster
configuration. Therefore, we propose a new solution to solve this problem
better.
