cassandra - Cassandra の 1.0 から 1.1 へのアップグレード

Question

Centos 5.5 で cassandra を 1.0.11-1 から 1.1.12-1 に更新しようとしています。http://www.datastax.com/docs/1.1/install/upgradingのドキュメントを読み、推奨される方法を試してみてください: yum install apache-cassandra11 でパッケージをインストールします。ただし、解決の問題が発生しています。

Cassandra を更新する正しい方法は、yum remove してから yum install することですか?

[root@cass01 ~]# yum install apache-cassandra11.noarch

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.
