配置hbase时，需注意lib下Hadoop依赖jar是否与当前hadoop的版本一致

安装实例：

hadoop：hbadoop-2.7.4

hbase：hbase-1.2.6

此时，hbase-1.2.6/lib下的Hadoop依赖jar即hadoop-*.jar均是2.5.1版本，因此需要把2.7.4版本的hadoop-*.jar进行替换。

步骤：

1）#先删除hbase-1.2.6/lib下Hadoop依赖jar

cd /home/hbase-1.2.6/lib

rm  –rf  /home/hbase-1.2.6/lib/hadoop-*.jar

2) #添加2.7.4的jar

cp /home/hadoop/hadoop-2.7.4/share/hadoop/common/lib/hadoop-annotations-2.7.4.jar                        /home/hadoop/hbase-1.2.6/lib/

cp /home/hadoop/hadoop-2.7.4/share/hadoop/yarn/hadoop-yarn-server-common-2.7.4.jar                       /home/hadoop/hbase-1.2.6/lib/

#hadoop-client-2.7.4.jar需要单独下载，因为一般是没有的
cp /home/hadoop/hadoop-client-2.7.1.jar                                                                                      /home/hadoop/hbase-1.2.6/lib/
