Subject [Lucene-hadoop Wiki] Trivial Update of "Hadoop 0.14 Upgrade" by RaghuAngadi
Date Wed, 22 Aug 2007 03:02:54 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Lucene-hadoop Wiki" for change notification.

The following page has been changed by RaghuAngadi:
http://wiki.apache.org/lucene-hadoop/Hadoop_0%2e14_Upgrade

------------------------------------------------------------------------------
  
  == Upgrade Path ==
  
- We have tested upgrading from 0.12 to 0.14 and 0.13.1 to 0.14. However we recommend upgrading
to 0.13.1 before this upgrade. Hadoop-0.13 adds an important upgrade related feature that
is very useful for upgrades like the one described here. While upgrading from 0.13, if something
badly goes wrong, you can always ''rollback'' to pre-upgrade state by installing 0.13 again.
See [:Hadoop Upgrade: Hadoop Upgrade page] for more information. Upgrading from 0.11 and earlier
version are very similar to upgrading from 0.12, but these cases are not extensively tested.
