确保可以上网，因为编译时要下载很多的jar 包

1、安装Maven

下载：apache-maven-3.0.5-bin.tar.gz

解压：[sparkadmin@hadoop4 ~]$ tar -zxvfapache-maven-3.0.5-bin.tar.gz

配置环境变量

[sparkadmin@hadoop4 ~]$ vim .bashrc

export MAVEN_HOME=/home/sparkadmin/apache-maven-3.0.5
export PATH=.:$PATH:$MAVEN_HOME/bin

刷新配置：

[sparkadmin@hadoop4 ~]$ source .bashrc

检查是否安装成功

[sparkadmin@hadoop4 ~]$ mvn

出现上面信息表示maven安装成功。

2、编译Flume

下载：apache-flume-1.5.0-src.tar.gz

[sparkadmin@hadoop4 ~]$ tar -zxvf apache-flume-1.5.0-src.tar.gz

Flume-ng 1.5.0 默认的Hadoop版本是1.0.1，Hbase是0.92.1，在编译时指定Hadoop2，默认的hadoop2是hadoop 2.4.0

加参数：-Phadoop-2

 <hadoop.version>1.0.1</hadoop.version>
 <hbase.version>0.92.1</hbase.version>

编译：

[sparkadmin@hadoop4 apache-flume-1.5.0-src]$ mvn install -Phadoop-2 -DskipTests -Dtar

报错解决办法：

第一个错误

[ERROR] Failed to execute goal on project flume-hdfs-sink: Could not resolve dependencies for project org.apache.flume.flume-ng-sinks:flume-hdfs-sink:jar:1.5.0: Failure to find org.apache.hadoop:hadoop-test:jar:2.4.0 in http://repo1.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of repo1.maven.org has elapsed or updates are forced -> [Help 1]

apache-flume-1.5.0-src/flume-ng-sinks/flume-hdfs-sink下面的pom.xml中注释掉：

<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-test</artifactId>
 <version>test</version>
</dependency>

第二个错误：

[ERROR] Failed to execute goal on project flume-ng-hbase-sink: Could not resolve dependencies for project org.apache.flume.flume-ng-sinks:flume-ng-hbase-sink:jar:1.5.0: Failure to find org.apache.hadoop:hadoop-test:jar:2.4.0 in http://repo1.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of repo1.maven.org has elapsed or updates are forced -> [Help 1]

apache-flume-1.5.0-src/flume-ng-sinks/flume-ng-hbase-sink下面的pom.xml中注释掉：

<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-test</artifactId>
<scope>test</scope>
</dependency>

第三个错误：

[ERROR] Failed to execute goal on project flume-tools: Could not resolve dependencies for project org.apache.flume:flume-tools:jar:1.5.0: Failure to find org.apache.hadoop:hadoop-test:jar:2.4.0 in http://repo1.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of repo1.maven.org has elapsed or updates are forced -> [Help 1]

apache-flume-1.5.0-src/flume-tools下面的pom.xml中注释掉：

<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-test</artifactId>
<scope>test</scope>
</dependency>

第四个错误：

[ERROR] Failed to execute goal on project flume-ng-morphline-solr-sink: Could not resolve dependencies for project org.apache.flume.flume-ng-sinks:flume-ng-morphline-solr-sink:jar:1.5.0: Failed to collect dependencies for [org.apache.flume:flume-ng-core:jar:1.5.0 (compile), org.slf4j:slf4j-api:jar:1.6.1 (compile), org.kitesdk:kite-morphlines-all:pom:0.12.0 (compile?), org.slf4j:jcl-over-slf4j:jar:1.6.1 (provided), org.apache.solr:solr-test-framework:jar:4.3.0 (test), org.kitesdk:kite-morphlines-solr-core:jar:tests:0.12.0 (test), junit:junit:jar:4.10 (test)]: Failed to read artifact descriptor for ua_parser:ua-parser:jar:1.3.0: Could not transfer artifact ua_parser:ua-parser:pom:1.3.0 from/to maven-twttr (http://maven.twttr.com): Failed to transfer file: http://maven.twttr.com/ua_parser/ua-parser/1.3.0/ua-parser-1.3.0.pom. Return code is: 504 , ReasonPhrase:Gateway Timeout. -> [Help 1]

这是因为：ua-parser-1.3.0下载失败

在根目录apache-flume-1.5.0-src 下面的pom.xml 中只需要加一个新的repository即可：

<repository>
  <id>p2.jfrog.org</id>
  <url>http://p2.jfrog.org/libs-releases</url>
</repository>

[sparkadmin@hadoop4 apache-flume-1.5.0-src]$ mvn install -Phadoop-2 -DskipTests -Dtar
