2. 압축풀기
tar xvfz apache-maven-3.2.5-bin.tar.gz
3. 링크걸기
ln -s apache-maven-3.2.5 maven
4. M2_HOME환경변수및 PATH 설정
vi /etc/profile
export M2_HOME=/usr/local/maven
export PATH=$PATH:$M2_HOME/bin
* 변경반영 : source /etc/profile
5. oozie 4.1다운로드
wget http://mirror.apache-kr.org/oozie/4.1.0/oozie-4.1.0.tar.gz
5-1. 기본적으로 hadoop 1.1.1을 기준으로 build되므로 hadoop 2.5.2로 컴파일 되도록 정보르 수정해준다.
6. 컴파일(default는 hadoop 1.1.1버젼으로 컴파일 되므로 -P hadoop-2를 지정하여 hadoop 2버젼으로 컴파일한다)
cd oozie-4.1.0/bin
./mkdistro.sh -P hadoop-2 -DskipTests
(컴파일 완료후 결과파일 생성위치 : /home/hadoop/oozie-4.1.0/distro/target/oozie-4.1.0-distro.tar.gz)
7. 6번 빌드파일을 설치할 위치로 복사후 압축풀기및 링크생성
cp ./oozie-4.1.0-distro.tar.gz /usr/local
cd /usr/local
tar xvfz oozie-4.1.0-distro.tar.gz
ln -s oozie-4.1.0/ oozie
8. war파일에 추가할 hadooplibs및 및 각종 jar파일 복사
mkdir libext
wget -P libext http://extjs.com/deploy/ext-2.2.zipcd libext
wget http://dev.sencha.com/deploy/ext-2.2.zip
cp -R ../oozie-4.1.0/hadooplibs/hadoop-2/target/hadooplibs/hadooplib-2.4.1.oozie-4.0.1/* libext
cp mysql-connector~.jar libext
* war파일 변경
[root@master oozie]$ oozie-setup.sh prepare-war
* 이전에 oozie-setup.sh 실행시 -extjs옵션을 주었는데 지금은 별도로 옵션을 주지 않고 libext폴더에 ext-2.2.zip파일을 복사애 놓고
oozie-setup.sh을 실행하면 자동으로 찾아서 설정해주는것으로 바뀌었다.

9. 환경변수 설정(/etc/profile)
export OOZIE_HOME=/hadoop/oozie
export PATH=$PATH:$OOZIE_HOME/bin
* 변경반영 : source /etc/profile

*아래 부분에 대한 주석을 풀어주고 #USER#값을 반드시 oozie실행 게정(예, hadoop 혹은 oozie)으로 변경한다.
(여기서 지정된것은 core-site.xml에 지정한 proxy와 반드시 일치할 필요가 없나?? 여기는 oozie로 하고 core-site.xml에는 hadoop
으로 지정해도 실행된다.??)
<property>
<name>oozie.service.ProxyUserService.proxyuser.#USER#.hosts</name>
<value>*</value>
<description>
List of hosts the '#USER#' user is allowed to perform 'doAs'
operations.
The '#USER#' must be replaced with the username o the user who is
allowed to perform 'doAs' operations.

12. 더비대신 mysql사용하도록 설정된 정보를 이용하여 db및 관련table생성
./ooziedb.sh create -sqlfile oozie.sql -run
13. 확인(command)
[root@master logs]$ oozie admin -oozie http://localhost:11000/oozie -status
System mode: NORMAL
14. 확인URL
http://master:11000/oozie/
* 어느정도 시간이 지나면 오류가 발생하면서 oozied가 다운되면서 catalina.out파일에
java.lang.NoClassDefFoundError: org/apache/hadoop/util/ShutdownHookManager라는 오류가 발생하면
hadoop의 common라이브러리를 oozie설치폴더의 lib에 복사하고(/usr/local/hadoop/share/hadoop/common/hadoop-common-2.5.2.jar /usr/local/oozie/lib), oozied.sh stop, oozied.sh start하여 oozie데몬을 다시 기동시켜준다.
