If you are running Cloudera Manager, you must upgrade to Cloudera Manager 5 to run CDH 5. Because Search 1.x is in a separate repository from CDH 4, you must remove the Search 1.x packages and the Search .repo or .list file before upgrading CDH. This is true whether or not you are upgrading through Cloudera Manager.

1. Remove the Search packages.
   The list of packages you may need to remove are:

   • solr
   • solr-doc
   • solr-mapreduce
   • hbase-solr
   • hbase-solr-doc
   • search
   1. Check which packages are installed using one of the following commands, depending on your operating system:

      rpm -qa               # RHEL, Oracle Linux, CentOS, Debian

      dpkg --get-selections # Debian

   2. Remove the packages using the appropriate remove command for your OS. For example:

      sudo yum remove solr solr-doc solr-mapreduce hbase-solr \
         hbase-solr-doc search      # RHEL, Oracle Linux, CentOS

2. Remove the Cloudera Search .repo or .list file:

   Operating System	File to remove:
   RHEL	/etc/yum.repos.d/cloudera-search.repo
   SLES	/etc/zypp/repos.d/cloudera-search.repo
   Ubuntu or Debian	/etc/apt/sources.list.d/cloudera.list

3. Upgrade from CDH 4 to CDH 5:
   • To upgrade using Cloudera Manager, see Upgrading CDH 4 to CDH 5. This assumes you have upgraded to Cloudera Manager 5.
   • To upgrade without using Cloudera Manager, see Upgrading from CDH 4 to CDH 5.
4. If you upgraded to CDH 5 without using Cloudera Manager, you need to install the new version of Search:

   Operating System	Command
   RHEL	sudo yum install solr-server
   SLES	sudo zypper install solr-server
   Ubuntu or Debian	sudo apt-get install solr-server
