    Description

      The current way for a DFS client to check or set safemode status is via the private DistributedFileSystem instances.

      While user/downstream (HBASE, PIG, HIVE) clients do not really need a way to "set" the safemode (doable by shell functions today), they can surely benefit from having a public API to check for safemode. Right now there is no way to do so.

      I plan to introduce a safemode check via a new public, evolving API "HDFSAdmin" (DFSAdmin already seems taken up by shell).

      (Part of HBASE-4510 can benefit from this, for example)
