I'm trying to create a connection via JDBC to Impala using the Hive2 connector. But I'm getting this error:
Exception in thread "main" java.lang.NoSuchFieldError: HIVE_CLI_SERVICE_PROTOCOL_V7
at org.apache.hive.jdbc.HiveConnection.<init>(HiveConnection.java:175)

at dsnoc.dsnoc_api.dsnoc.main(dsnoc.java:75)
I don't know if it is a depencency compatibility issue:
<dependency>
<groupId>org.apache.hive</groupId>
<artifactId>hive-exec</artifactId>
<version>1.1.0</version>
</dependency>
<dependency>
<groupId>org.apache.hive</groupId>
<artifactId>hive-jdbc</artifactId>
<version>1.1.0</version>
</dependency>
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-common</artifactId>
<version>2.6.0</version>
</dependency>
I'm using CDH 5.8.0 with Hive 1.1.0 and Hadoop 2.6.0
Or maybe is Code issue:
public static double getDolarFromImpala(String date) {
double dolar = 0.0;
try {
Class.forName(JDBC_DRIVER_HIVE);
String sql = "SELECT valor FROM dolar where fecha ='"+date+"'";
Connection con = DriverManager.getConnection(JDBC_HIVE2_URL,USERNAME,PASSWORD);
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery(sql);
while(rs.next()){
dolar = rs.getDouble("valor");
}
stmt.close();
con.close();
}
catch(SQLException se){
//Handle errors for JDBC
se.printStackTrace();
}
catch(Exception e){
//Handle errors for Class.forName
e.printStackTrace();
}
return dolar;
}
But I think is not, because I tried it with an Impala-JDBC and worked.
Other thing is that I'm not using the Impala-JDBC because it don't reads or sends the USERNAME
and PASSWORD
, throwing me this error:
[Simba][ImpalaJDBCDriver](500051) ERROR processing query/statement. Error Code: 0, SQL state: TStatus(statusCode:ERROR_STATUS, sqlState:HY000, errorMessage:AuthorizationException: User '' does not have privileges to execute 'SELECT'
