i used follwoing documentation same cloudera: https://www.cloudera.com/documentation/other/connectors/hive-jdbc/2-5-4.html appreciated. trying following connection string :- connection con = drivermanager.getconnection("jdbc:hive2://server.com:12345/default;principal=hive/_org.com","user_id","pwd");

the complete code : 

package hive2; import java.sql.sqlexception; import java.sql.connection; import java.sql.resultset; import java.sql.statement;   import java.sql.drivermanager;  public class hive {   private static string drivername = "com.cloudera.hive.jdbc4.hs2driver";    public static void main(string[] args) throws sqlexception {     try {       class.forname(drivername);     } catch (classnotfoundexception e) {       // todo auto-generated catch block       e.printstacktrace();       system.exit(1);     }         connection con = drivermanager.getconnection("jdbc:hive2://server.com:12345/default;principal=hive/_org.com","user_id","pwd");     statement stmt = con.createstatement();     string tablename = "testhivedrivertable";     stmt.executequery("drop table " + tablename);     resultset res = stmt.executequery("create table " + tablename + " (key int, value string)");     // show tables     string sql = "show tables '" + tablename + "'";     system.out.println("running: " + sql);     res = stmt.executequery(sql);     if (res.next()) {       system.out.println(res.getstring(1));     }     // describe table     sql = "describe " + tablename;     system.out.println("running: " + sql);     res = stmt.executequery(sql);     while (res.next()) {       system.out.println(res.getstring(1) + "\t" + res.getstring(2));     }      // load data table     // note: filepath has local hive server     // note: /tmp/a.txt ctrl-a separated file 2 fields per line     string filepath = "/tmp/a.txt";     sql = "load data local inpath '" + filepath + "' table " + tablename;     system.out.println("running: " + sql);     res = stmt.executequery(sql);      // select * query     sql = "select * " + tablename;     system.out.println("running: " + sql);     res = stmt.executequery(sql);     while (res.next()) {       system.out.println(string.valueof(res.getint(1)) + "\t" + res.getstring(2));     }      // regular hive query     sql = "select count(1) " + tablename;     system.out.println("running: " + sql);     res = stmt.executequery(sql);     while (res.next()) {       system.out.println(res.getstring(1));     }   } }

driver class in code odbc driver, cannot used jdbc connection hiveserver2. refer below apache hive url jdbc connection.

below sample code snippet hiveserver2 jdbc connection.

https://cwiki.apache.org/confluence/display/hive/hiveclient#hiveclient-jdbc

dependent jar given in documentation, can find these dependent jars in hive lib path. (/opt/cloudera/cdh/hive/lib/*)

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
