如何用hive api导入数据

Class.forName("org.apache.hadoop.hive.jdbc.HiveDriver");

Connection con = DriverManager.getConnection("jdbc:hive://192.168.191.17:10000/default", "", "");

Statement stmt = con.createStatement();

String sql = "LOAD DATA LOCAL INPATH '/data/mf/hzip/tmp/gamecoins' INTO TABLE gamecoins_stream";

ResultSet rs = stmt.executeQuery(sql);

while(rs.next()) {

System.out.println(rs.getInt(0));

}

rs.close();

stmt.close();

con.close();

?

注意：这个文件的路径是要在开启以下命令的机器上

[hadoop@Hadoop-10-1 hive]$ bin/hive --service hiveserver &

?

否则，执行时会出现文件路径不存在的情况：

HiveServerException(message:Query returned non-zero code: 40000, cause:?

FAILED: SemanticException Line 1:23 Invalid path ''/data/mf/hzip/tmp/gamecoins'':?

No files matching path file:/data/mf/hzip/tmp/gamecoins, errorCode:40000, SQLState:42000)
