--------------------------------------------
Summary: Disallow nested snapshottable directories
Key: HDFS-4758
URL: https://issues.apache.org/jira/browse/HDFS-4758
Project: Hadoop HDFS
Issue Type: Sub-task
Components: namenode
Reporter: Tsz Wo (Nicholas), SZE
Assignee: Tsz Wo (Nicholas), SZE
Nested snapshottable directories are supported by the current implementation.
However, it seems that there are no good use cases for nested snapshottable
directories. So we disable it for now until someone has a valid use case for
it.
