> BlockManagerSafeMode is doing wrong parsing for safemode threshold. It is
> storing float value in double, which will give different result some time. If
> we store "0.999f" value in double then it will be converted to
> "0.9990000128746033".
> {code:java}
> this.threshold = conf.getFloat(DFS_NAMENODE_SAFEMODE_THRESHOLD_PCT_KEY,
> DFS_NAMENODE_SAFEMODE_THRESHOLD_PCT_DEFAULT);{code}
