Harsh J resolved HDFS-2466.
---------------------------
Resolution: Duplicate
Sorry, this is a dupe of HDFS-2413
> Need a public way to check DFS Safemode status
> ----------------------------------------------
>
> Key: HDFS-2466
> URL: https://issues.apache.org/jira/browse/HDFS-2466
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs client
> Affects Versions: 0.23.0
> Reporter: Harsh J
> Assignee: Harsh J
> Priority: Critical
>
> 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)
