== Apache HBase ==


=== mysql ===
Apache HBase is Bigtable like data store, built on top of Hadoop.


MySQL has been updated to 5.1.x.  This represents a major version upgrade from Fedora 10's 5.0.x release series.
You should test database-using applications for possible incompatibilities.  Upstream's release notes can be found at
[http://dev.mysql.com/doc/refman/5.1/en/news-5-1-x.html].


If you are upgrading a Fedora 10 installation that includes a live 5.0.x MySQL database, don't forget to run mysql_upgrade after completing the software upgrade.  There is a [https://bugzilla.redhat.com/show_bug.cgi?id=493160 report] that this may fail altogether if the 5.0.x database had been updated from an even older installation without running mysql_upgrade at the time.  If you think this might be the case for your database, it is prudent to run mysql_upgrade on the Fedora 10 installation before upgrading.  (And, of course, you should have backups if the database content is at all critical.)
== Apache Hive ==


=== postgresql ===
Apache Hive is a Hadoop based NoSQL data warehouse.
 
Fedora 11 includes version 8.3.7 of  PostgreSQL.  This is the same version currently shipped in Fedora 10 and Fedora 9;
you should not notice any significant difference if you are upgrading from an up-to-date F-10 or F-9 installation.
Otherwise, please see upstream's release notes at [http://www.postgresql.org/docs/8.3/static/release.html].
