【成功】maven編譯 apache falcon0.9源碼_RedHat6.4

事前准備

apache falcon源碼（本次使用的是最新的apache-falcon-0.9-sources.tar.gz）
jdk(1.7/1.8)maven(3.X) apache-maven-3.0.3-bin.tar.gz 【後續提示出錯，換成maven3.1.0】

安裝

JDK

JDK的安裝，此處就不再說明了，很簡單，裝完後記得配置/etc/profile裡JAVA_HOME，完後source一下就OK了，確認如下：

[root@sv004 project]# java -version
java version "1.7.0_67"
Java(TM) SE Runtime Environment (build 1.7.0_67-b01)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)

maven

maven的安裝，本人第一次，也很簡單，解壓，配置MAVEN_BIN，然後使用mvn -v確認是否安裝。效果如下所示：

[root@sv004 apache-maven-3.0.3]# ./bin/mvn -v
Apache Maven 3.0.3 (r1075438; 2011-03-01 02:31:09+0900)
Maven home: /home/project/apache-maven-3.0.3
Java version: 1.7.0_67, vendor: Oracle Corporation
Java home: /usr/java/jdk1.7.0_67/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "2.6.32-431.el6.x86_64", arch: "amd64", family: "unix"

本次的重點來了

使用maven編譯falcon源碼

1.解壓falcon源碼

tar -xzvf apache-falcon-${project.version}-source.tar.gz
cd falcon-sources-${project.version}

2.編譯falcon

export MAVEN_OPTS="-Xmx1024m -XX:MaxPermSize=256m -noverify" && mvn clean install

但此時報錯了

原因

根據Unkown host信息調查了一下，應該是代理設置的有問題，我的maven使用的是默認的，沒有設置，坑就被我踩到了。

參考URL:http://stackoverflow.com/questions/15334394/could-not-transfer-artifact-org-apache-maven-pluginsmaven-surefire-pluginpom2/15334627#15334627

解決策

修改我的maven/conf/setting.xml，如下所示：

  
     
      true
      http
      ***.***.***.***  ?代理的IP地址
      8080
      maven

完後重新執行

export MAVEN_OPTS="-Xmx1024m -XX:MaxPermSize=256m -noverify" && mvn clean install

第一次時間比較長，取決你的網速，因為要下載好多依賴包文件。

好事多磨呀.....

根據報錯信息來看，maven的版本與下載的插件的版本不一致導致的，根據提示信息，遂決定使用maven3.1.0。

構建好Maven3.1.0的環境後，重新再次編譯falcon源碼，結果悲劇了，install-node-and-npm無法下載.......

調查了好久，最終來發現，原來是磁盤沒有空間了，剛開始還以為是公司的網速的問題

清空一部分空間出來後，又出幺蛾子了.....

還有一個額外的信息：Exception while executing SCM command.

最後在英文網站上找到了一個解決策，但原因是什麼，沒有明白。

Find the lines that read:

org.codehaus.mojo
buildnumber-maven-plugin
1.0

and remove them.

但，新的問題又出現了，打出的堆棧信息如下所示....

根據上面的提示信息，找到一個對應的帖子：

http://mail-archives.apache.org/mod_mbox/falcon-dev/201402.mbox/%[email protected]%3E

https://issues.apache.org/jira/browse/FALCON-291

看著是Falcon的一個降級BUG，發郵件詢問Falcon社區的負責人，一天過去了，沒有回信。

自己動手去琢磨，falcon0.4作入的BUG，0.9的話，應該是已經被修正了，估計是自己這邊的環境有問題，再繼續折騰吧，找到解決策後再繼續追加。

全局使用maven編譯的時候，一直報錯

Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec (BUILD-OOZIE)

但具體是哪有問題，即使使用mvn clean install -X打印出詳細的堆棧信息，對於不清楚源碼的人來說，還是沒有什麼實質性的幫助。遂決定單獨去編譯build-tool模塊。

單獨編譯build-tool時，出錯信息就詳細多了，且很有價值的信息。具體如下所示：

看到上面黑體加錯的那三行，就知道是什麼原因造成build-tool一直無法編譯了。

getaddrinfo(3)出錯導致的。

繼續解析，發現是自己的虛擬機沒有配DNS，或者說，沒有在虛擬機中設置代理。可悲的是，下班後坐在車上才想通了，原來只需要在UI界面設置一下代理，就可以下載這個http://archive.apache.org/dist/oozie/4.1.0/oozie-4.1.0.tar.gz文件了。可惜，下班之前沒有搞定，只能下周一接著去確認了。

@2016/04/18

今天到公司後，配好虛擬機的代理。能上網，但就是ping不通www.baidu.com。主機這邊也是ping不通www.baidu.com。猜測應該是整個公司將DNS的解析給屏蔽掉了。再次執行mvn clean install，還是出問題，但在vmware下執行的時候，之前的錯誤就沒發生，這會一直處於關聯文件下載中，對公司的網速表示呵呵了。但沒報錯就是好事了....

新的問題又出現了，在build testcase的時候出錯了。。。

因為本次編譯的重點是falcon源碼，至於自帶的測試項，對後續的使用是沒有用處的，換句話說，編譯測試項，只是進一步證明了而已，為了，解決方案是跳過它。

解決命令：

export MAVEN_OPTS="-Xmx1024m -XX:MaxPermSize=256m -noverify" && mvn clean install -Dhadoop.version=2.5.2 -DskipTests

再次執行，編譯又可以繼續了，又是不停的下載關聯的文件的模式了......

但，還是看到了希望

至此，apache falcon的源碼終於編譯成功了。

部署嵌入式模式：

命令：

mvn clean assembly:assembly -DskipTests -DskipITs

位置：{project dir}/target/apache-falcon-${project.version}-bin.tar.gz

* tar -xzvf apache-falcon-${project.version}-bin.tar.gz
* cd falcon-${project.version}

啟動falcon：

bin/falcon-start

Hadoop home is set, adding libraries from '/home/project/hadoop-2.5.2/bin/hadoop classpath' into falcon classpath
/home/project/apache-maven-3.3.9/falcon-sources-0.9/target/falcon-0.9
falcon started using hadoop version:  Hadoop 2.5.2

注意點：
falcon.url=https://localhost:15443/

firfox或者chorme或者IE9以上登錄，追加認證後就可以顯示falcon的畫面了。

感觸：

1.本次的搭建環境從頭到尾，制約因素最大的就是網速了

2.虛擬機的DNS和代理沒有配置，導致開始building時沒有准確的定位到。以為設置了maven的代理，應該就沒事了。

3.沒有善用-x參數，在解析maven.apche.org的時候，不知所措。
