我正在尝试连接到安装在ubuntuvm上的远程hbase-0.94.8。我在开玩笑 TableNotFoundException 这是我的java代码：

Configuration config = HBaseConfiguration.create();
config.set("hbase.zookeeper.quorum", "192.168.56.101");
HTableInterface usersTable = new HTable(config, "users");

以下是完整的异常跟踪：

你可以在使用前检查一下table。为此，您可以使用hbaseadmin。创建hbaseadmin示例并使用istableavailable（string tablename）方法。

Configuration config = HBaseConfiguration.create();
config.set("hbase.zookeeper.quorum", "192.168.56.101");
HBaseAdmin admin = new HBaseAdmin(config);
if(admin.isTableAvailable(tableName))
{
  HTableInterface usersTable = new HTable(config, "users");
}

我希望它能帮助你。
