Upgrade from 0.16.3 to 0.17.0

I have upgraded from 0.16.3 to 0.17.0 correctly. But after a few days
the disk usage has been increased. I have notice that there are two
folder in the data nodes:

- current -> With version -13
- previous -> With version -11

And I have this message in the HDFS webapp: 

Upgrade for version -13 has been completed. Upgrade is not finalized.

Questions:

1) Is that normal?
2) Could the upgrade increase the disk usage?
3) Is there any way to finish the upgrade? Any command to force it?
4) Could I delete the previous folder?

Thanks,

Thanks! 

The -finalizeUpgrade command worked properly.

1) Yes, that is normal.  You have to manually finalize the upgrade.
2) Probably, because (as I understand it), it keeps a backup of the
pre-upgraded state.
3) you can use hadoop dfsadmin -finalizeUpgrade to finalize it.  See
here: http://wiki.apache.org/hadoop/Hadoop_Upgrade
4) I assume the finalizeUpgrade command will do that for you.
