Metatron 로컬 개발환경 설정

설치전 준비

 cd /
 sudo mkdir -p /Development/Hadoop
 sudo chown -R -v '오너 이름' /Development/
 mv '해당 프로젝트 다운로드 경로'/metatron-settings /Development/

MariaDB 설치

 brew update
 brew install mariadb
 brew services start mariadb

 # MariaDB 실행 관련 명령어
 # mysql.server status # 상태확인
 # mysql.server stop   # 정지
 # mysql.server start  # 실행
 # mysql -uroot        # 접속

DB 생성 ( MySQL의 DB 생성 권한이 있는 계정으로 실행 )

 mysql -uroot

Hadoop 설치

 cd /Development/Hadoop/
 wget http://apache.tt.co.kr/hadoop/common/hadoop-2.7.6/hadoop-2.7.6.tar.gz
 tar zxvf hadoop*.tar.gz
 mv hadoop-2.7.6.tar.gz ../

 # JAVA_HOME이 잡혀 있지 않은 경우 JAVA_HOME 추가
 # 확인은 편집창을 나가서 `echo $JAVA_HOME` 으로 확인가능

 # e.g )
 # export JAVA_HOME=“/Library/Java/JavaVirtualMachines/jdk1.8.0_73.jdk/Contents/Home”
 # “/Library/Java/JavaVirtualMachines/jdk1.8.0_73.jdk/Contents/Home”는 자신의 경로로 바꿔준다

Hive 관련 설정

하이브 메타스토어 테이블 생성 및 권한 부여

create database hive_metastore_db;
grant all privileges on . to 'hive'@'localhost' identified by 'hive' with grant option;
grant all privileges on . to 'hive'@'%' identified by 'hive' with grant option;
grant all privileges on hive_metastore_db.* to 'hive'@'%' identified by 'hive';
flush privileges;

생성확인

select host from mysql.user where user='hive';

Druid 설정

  • 드루이드는 메타트론 프로젝트의 README 확인후 변경 필요: 오늘 날짜로 druid-0.9.1-latest-hadoop-2.7.3-bin.tar.gz 이 최신 버젼
  • 다운로드 링크 확인하는 방법 : 메타트론 프로젝트의 README > Installation > Druid customized version for Metatron 링크주소 확인 스크린샷 2019-01-17 오후 6.45.54
  • 아래 스크립트의 드루이드 바이너리 이름은 메타트론 프로젝트에서 제공하는 바이너리 버젼에 따라 적절히 변경이 필요
 cd /Development/Hadoop/
 mkdir druid
 cp ../metatron-settings/druid* druid
 cd druid
 unzip druid_bootstrap_init.zip
 tar zxvf druid-0.9.1-latest-hadoop-2.7.3-bin.tar.gz
 ./init.sh druid-0.9.1-SNAPSHOT.3.1.0.201812070238-hadoop-2.7.3
 cd druid
 ./start-single.sh
 cd ..
 cp ../../metatron-settings/ingestion.zip .
 unzip ingestion.zip
 cd ingestion

 #

 ./run_index.sh index_sales_join_category_spec.json

start-all.sh / stop-all.sh 복사

 cd /Development/Hadoop/
 cp ../metatron-settings/start-all.sh .
 cp ../metatron-settings/stop-all.sh .

여기까지가 메타트론 설정입니다.

아래는 드루이드 엔진 버젼 패치 가이드

Druid 엔진 패치시

1. 드루이드 정지
2. 드루이드 심볼릭 링크 제거
3. [드루이드 설정](https://gitlab.com/metatron/metatron-settings#druid-%EC%84%A4%EC%A0%95)
 - start-single.sh 까지만 하시면 됩니다.
