Java连接HBase问题

[qq_22884313]

我用windows上的maven工程连接虚拟机上的hbase时报错
Exception in thread "main" org.apache.hadoop.hbase.client.RetriesExhaustedException: Can't get the locations
看网上有人说这个问题是配置问题 我已经把HBase集群的主机名和ip都加到hosts里面了 还是没有作用 以下是hbase-site 和core-site的配置 跪求大神帮忙啊

贴操作hbase的代码看看 configuration.set("hbase.zookeeper.quorum", zookeeper地址)

Configuration config = HBaseConfiguration.create(); config .set("hbase.zookeeper.quorum", zookeeper地址) 我用的0.96版本 是要在config里set一下zookeeper的地址

这个在1.2.5的版本不行
