Issues with V0.19 upgrade 

1. The namenode webpage shows:

   Upgrades: Upgrade for version -18 has been completed. 
   Upgrade is not finalized. 

2. SequenceFile.Writer failed when trying to creating a new file with the following error: (we have two HaDoop clusters, both have issue 1; one has issue 2, but the other is fine on issue 2). Any idea what's going on?

Thanks,

Not sure if anyone else answered...

1. You need to run hadoop dfsadmin -finalizeUpgrade.  Be careful, because you can't go back once you do this.

I don't know about 2.
