----------------------------------
Summary: RBF: Choose to enable the default nameservice to write
files.
Key: HDFS-13857
URL: https://issues.apache.org/jira/browse/HDFS-13857
Project: Hadoop HDFS
Issue Type: Improvement
Components: federation, hdfs
Affects Versions: 2.9.1, 3.1.0, 3.0.0
Reporter: yanghuafeng
Assignee: yanghuafeng
The default nameservice can provide some default properties for the namenode
protocol. And if we cannot find the path, we will get a location in default
nameservice. From my side as cluster administrator, we need all files to be
written in the location from the MountTableEntry. If no responding location,
some error will return. It is not better to happen some files are written in
some unknown location. We should provide a specific parameter to enable the
default nameservice to store files.
