011-Ambari二次開發之元件編譯概述

Ambari元件即大資料生態圈的元件，如Hadoop，Zookeeper，HBase，Hive，Spark，Kafka等。當我們業務需要修改原始碼時，我們需要重新編譯打包元件。Ambari的元件包是以RPM包的形式存在的，並且Ambari元件包檔案路徑存放位置和原生方式安裝是不同的，所以我們要重新打包Ambari元件包，首先要了解Ambari元件包的組成方式，或者想辦法修改最小的部分。

具體思路，只供參考，可能還有其他的辦法。
1. 編譯需要重新打包的元件。
2. 解壓Ambari元件包即RPM包。
3. 我們在重新打成RPM包時，我們在前面文章提到過需要打到包裡的原始檔案以及SPEC檔案。原始檔案，我們通過2解壓完後，可以將1中編譯的檔案拷貝進去，打成tar.gz即可，SPEC檔案組織比較困難，因為SPEC檔案是用來組織包結構以及版本，描述等資訊，之前在github上面有開源的bigtop的方式，但是在後續版本沒有再更新，這條路基本不通。只能使用比較投機的辦法。我們可以將RPM包安裝在某一臺機器上，然後通過rpmrebuild命令可以直接提取，但是這種方式提取出來的SPEC檔案是將每個檔案的路徑，許可權都顯示出來了，雖然比較lower，但是不影響結果。當然網上還有其他方式，如rpm2cpio。
4. 有了原始檔案，SPEC檔案，我們就可以通過rpmbuil重新打出RPM包。

下面我們以Zookeeper為例，來說明具體的方法。
1. 重新編譯Zookeeper原始碼，下一篇我們將介紹如何編譯Zookeeper原始碼，此處暫定。我們假設我們已經編譯完Zookeeper，並且我們要替換原始RPM包中的zookeeper-3.4.6.2.6.2.0-205.jar
2. 解壓Ambari自帶的zookeeper_2_6_2_0_205-3.4.6.2.6.2.0-205.noarch.rpm

解壓後的部分目錄結構

3. 安裝zookeeper_2_6_2_0_205-3.4.6.2.6.2.0-205.noarch.rpm 提取SPEC檔案
我們在安裝時發現需要依賴hdp-select包，所以我們先安裝hdp-select

%description
ZooKeeper is a centralized service for maintaining configuration information,
naming, providing distributed synchronization, and providing group services.
All of these kinds of services are used in some form or another by distributed
applications. Each time they are implemented there is a lot of work that goes
into fixing the bugs and race conditions that are inevitable. Because of the
difficulty of implementing these kinds of services, applications initially
usually skimp on them ,which make them brittle in the presence of change and
difficult to manage. Even when done correctly, different implementations of these services lead to management complexity when the applications are deployed.

    011-Ambari二次開發之元件編譯概述
       
  
  
 Ambari元件即大資料生態圈的元件，如Hadoop，Zookeeper，HBase，Hive，Spark，Kafka等。當我們業務需要修改原始碼時，我們需要重新編譯打包元件。Ambari的元件包是以RPM包的形式存在的，並且Ambari元件包檔案路徑存放位置和原生方式安裝是不同的，所以我們 

  
 

    

    
    012-Ambari二次開發之元件Zookeeper，Kafka，Hadoop編譯
       
  
  
 Zookeeper是大資料生態圈元件之間協調的基礎元件。本篇我們開始編譯基於HDP3.0版本棧的Zookeeper。 關注微信公眾號，獲取更多內容  Zookeeper編譯 
  
  安裝ant，Zookeeper依賴於ANT編譯，所以需要安裝ant yum install ant

 在介紹如何修改棧名稱之前，我們先要了解一下stack的相關概念及在什麼情況下需要修改棧名稱。  掃描二維碼，關注BearData，獲取最新文章    Ambari-stack 表示HDP的某個發行版本，例如HDP-1.0.0，在用ambari建立一個叢集時，首先要通過呼叫restfulAPI 

  
 

    

    
    006-Ambari二次開發之web環境搭建除錯
       
  
  
 當我們需要修改前端樣式時，我們需要搭建web本地除錯環境，本篇我們將介紹如何在本地搭建web開發環境。
