5）问题

如果执行flume-ng 的时候执行报错：Caused by: Java.lang.ClassNotFoundException: org.apache.flume.tools.GetJavaProperty

一般来说是由于jdk版本造成的，改为JDK7版本就好了

错误: 找不到或无法加载主类 org.apache.flume.tools.GetJavaProperty或者Error: Could not find or load main class org.apache.flume.tools.GetJavaProperty

一般来说是由于装了Hbase等工具的原因

flume运行flume-ng version时报错信息：

Exception in thread "main" Java.lang.NoClassDefFoundError: org/apache/flume/tools/GetJavaProperty

Caused by: java.lang.ClassNotFoundException: org.apache.flume.tools.GetJavaProperty

        at java.NET.URLClassLoader$1.run(URLClassLoader.java:202)

        at java.security.AccessController.doPrivileged(Native Method)

        at java.lang.ClassLoader.loadClass(ClassLoader.java:247)

Could not find the main class: org.apache.flume.tools.GetJavaProperty.  Program will exit.

解决：将你的jdk6变成jdk7

变成jdk7后报错变为：

错误: 找不到或无法加载主类 org.apache.flume.tools.GetJavaProperty

将你的Hbase配置文件的hbas-env.sh中的配置变为：

1、将hbase的hbase.env.sh的一行配置注释掉

# Extra Java CLASSPATH elements. Optional.

#export HBASE_CLASSPATH=/home/hadoop/hbase/conf

2、或者将HBASE_CLASSPATH改为JAVA_CLASSPATH,配置如下

# Extra Java CLASSPATH elements. Optional.

export JAVA_CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
