hadoop-hbase错误，搞了很久终于有结果了

hbase错误。。搞了很久，发现网上没找到，写上篇文章给大家点小福利

hbase创建成功了，能够在服务器上运行hbase shell创建表了，但是用eclipse客户端连就连不上，错误如下

Exception in thread "main" org.apache.hadoop.hbase.client.RetriesExhaustedException: Failed after attempts=35, exceptions:

找服务器linux上运行hostname，发现是localhost，原因就出在这，全部hadoop机器hostname都要换成别名，我的是master，slave1。。。。。。因此上网百度一下linux hostname更改就可以找到方法了，但问题是要重启服务器才行，我又不想重启，所以运行master机器上运行 hostname master，slave1机器上运行hostname slave1 。。。。。，重启hbase后就ok了。不知道能不能帮到各位碰上这问题的骚年
