我在c:\hadoop2.5.2中安装hadoop，然后在c:\hadop2.5.2\apache-flume-1.6.0下解压其中的flume二进制文件
我得到的错误如下所示有什么想法吗？

C:\hadoop2.5.2\apache-flume-1.6.0\bin>flume-ng agent -conf -f conf/flume-twitter.conf -Dflume.root.logger=DEBUG,console -n TwitterAgent

C:\hadoop2.5.2\apache-flume-1.6.0\bin>

我在flume.sh中设置了参数

export JAVA_HOME=C:\Java\jdk1.7.0_79\

# Give Flume more memory and pre-allocate, enable remote monitoring via JMX

export JAVA_OPTS="-Xms100m -Xmx2000m -Dcom.sun.management.jmxremote"

# Note that the Flume conf directory is always included in the classpath.

FLUME_CLASSPATH="C:\hadoop2.5.2\apache-flume-1.6.0\lib\flume-sources-1.0-SNAPSHOT.jar"

你们知道怎么解决吗？
