flume打包遇到的一些问题
1.ipc兼容性问题，线上使用2.3.0的hdfs，但是打包时默认为1.2.1的

拷贝hadoop-core包即可,或者更改pom.xml文件

<properties>
<hadoop.version>1.2.1</hadoop.version> //hadoop-core-1.2.1.jar 改为hadoop-core-2.3.0-mr1-cdh5.1.0.jar
<hbase.version>0.92.1</hbase.version>
<hadoop.common.artifact.id>hadoop-core</hadoop.common.artifact.id>
<thrift.version>0.7.0</thrift.version>
</properties>
|
或者打包时指定：
|
1
|
mvn clean install -Phadoop-2 |
2.没有跳过test时
|
1
|
org.apache.flume.auth.TestFlumeAuthenticator: org/apache/commons/io/Charsets (no class error) |
根目录下的pom.xml文件中更改为:
|
1
2
3
4
5
|
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.4</version> //2.1的包没有Charsets这个类
</dependency>
|
如果手动下载jar包可以使用如下命令导入：
|
1
|
mvn install:install-file -DgroupId=commons-io -DartifactId=commons-io -Dversion=2.0.1 -Dpackaging=jar -Dfile=commons-io-2.4.jar |
3. 程序语言问题，因为在系统中使用了中文环境导致编译不通过

@Test public void shouldUseUtcAsBasisForDateFormat() {
assertEquals("Coordinated Universal Time",
factory.fastDateFormat.getTimeZone().getDisplayName()); //请求英文，返回中文
}

@Test public void testCarrotDateFormatBug() throws Exception {
SimpleDateFormat formatterFrom = new SimpleDateFormat("EEE MMM dd HH:mm:ss Z yyyy"); //更改为new SimpleDateFormat("EEE MMM dd HH:mm:ss Z yyyy",Locale.US);
formatterFrom.parse("Fri Oct 26 22:53:55 +0000 2012");
}
|
或者简单点，更改语言设置或者直接skip test
|
1
|
mvn clean install -Phadoop-2 -DskipTests |
4.json问题
替换单个jar包时，因为依赖问题，包class not found:
