> HDFS-1477 provides an option to reconfigured namenode heartbeat interval without restarting
the namenode. When the heartbeat interval is reconfigured, {{blockInvalidateLimit}} gets recounted
> {code}
>  this.blockInvalidateLimit = Math.max(20 * (int) (intervalSeconds),
>         DFSConfigKeys.DFS_BLOCK_INVALIDATE_LIMIT_DEFAULT);
> {code}
> this doesn't honor the existing value set by {{dfs.block.invalidate.limit}}.
