liying updated HDFS-17256:
--------------------------
Description:
In general, we do not need to set isolation limits for all namespaces in
cluster. For example, we only need to set the isolation limits for the problem
namespaces to avoid affecting other namespaces when some namespaces occur
errors. If we set isolation limits for all namespaces in cluster, it brings
many risks by itself as it is very difficult to confirm the specific
parameters. Instead，The result is increasing request latency for other
namespaces. Let's talk about a specific scenario:
when ns1 service is unavailable as some bugs，we turn on isolation-related
switches dynamically to support the abnormal ns isolation in router ， and set
the handler number of abnormal ns as low as possible to avoid affecting other
namespaces.
> add the individual namespaces isolation mode for router to avoid affecting
