> After HDFS-17231, NameNode can exit safemode automatically when resources are
> from low to available. It used
> org.apache.hadoop.hdfs.server.namenode.FSNamesystem#leaveSafeMode, this
> function will change BMSafeModeStatus. However, NameNode entering resource
> low safe mode doesn't change BMSafeModeStatus in
> org.apache.hadoop.hdfs.server.namenode.FSNamesystem#enterSafeMode. This is
> not equal
> Now:
> a. NN enter StartupSafeMode
> b. NN enter ResourceLowSafeMode
> c. NN resources from low to available
> d. NN safemode off
>
> Expectations：
> a. NN enter StartupSafeMode
> b. NN enter ResourceLowSafeMode
> c. NN resources from low to available
> d. NN exit ResourceLowSafeMode but in StartupSafeMode
