在win上的eclipse进行配置hbase，然后编写一个简单的创建表的操作，使用ant的build.xml进行运行报错：

[sshexec] Connecting to 192.168.60.111:22

  [sshexec] cmd : /opt/hadoop/bin/hadoop jar /home/hadoop_jar/HbaseApp1.jar hbasetest.HbaseApp1

  [sshexec] Exception in thread "main" 

  [sshexec] java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/HBaseConfiguration

  [sshexec]

但是不使用build时，直接点击右键运行时，没有报错：

log4j:WARN No appenders could be found for logger (org.apache.hadoop.metrics2.lib.MutableMetricsFactory).

log4j:WARN Please initialize the log4j system properly.

log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

table exists

解决办法：

 在hadoop-env.sh文件中增加如下代码

  export HADOOP_CLASSPATH=/usr/local/hbase-0.98.8-hadoop2/lib/*
