Solr (HDP Search) を6.6.2にアップグレード

Ref: https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.4/bk_solr-search-installation/content/ch_hdp_search_30.html

https://doc.lucidworks.com/lucidworks-hdpsearch/3.0.0/Guide-Solr-Upgrade.html#upgrade-the-solr-stack-ambari-mpack

アップグレードをテストするために古いバージョンをインストール

wget http://public-repo-1.hortonworks.com/HDP-SOLR/hdp-solr-ambari-mp/solr-service-mpack-2.2.8.tar.gz
ambari-server install-mpack --mpack=./solr-service-mpack-2.2.8.tar.gz
ambari-server restart
# Install Solr from Ambari Web UI normally

ブラウザーから、現在のコンフィグを取っておく（後で比較する）

アップグレード

wget http://public-repo-1.hortonworks.com/HDP-SOLR/hdp-solr-ambari-mp/solr-service-mpack-3.0.0.tar.gz

ambari-server upgrade-mpack --mpack=./solr-service-mpack-3.0.0.tar.gz

ambari-server restart

新しいrepoファイルをダウンロード（追記：repoinfo.xmlが正しい場合は必要ないかも？）

curl -o /etc/yum.repos.d/hdp-solr.repo http://public-repo-1.hortonworks.com/HDP-SOLR-3.0.0-100/repos/centos6/hdp-solr.repo

ちなみに、下記ファイルは同じではないが、シムリンクでsolr-ambari-mpack-3.0.0以下にある
