jdbc - How to set Hive configuration property hive.exec.dynamic.partition from Java code -


i have made java script connect hive using hiveserver2 , create table , manage tables, simple create, drop, insert data works fine.

i want create external table partition, need change value following hive property,

hive.exec.dynamic.partition = true hive.exec.dynamic.partition.mode = nonstrict

in hive cli can using set , property name, how can done in java code.

here java code:

 public class hivejdbcclient {      private static string strdrivername = "org.apache.hive.jdbc.hivedriver";     public static void main(string[] args) throws sqlexception {         try{         class.forname(strdrivername);         } catch (classnotfoundexception e){             e.printstacktrace();             system.out.println("no class found");             system.exit(1);         }         connection con = drivermanager.getconnection("jdbc:hive2://172.11.1.11:10000/default","root","root123");         statement stmt = con.createstatement();         string strtablename = "testtable";          //stmt.execute("drop table " + strtablename);         //creating staging table load data partition data          string strstagingtablesql = "create table if not exists "+strtablename+"_staging "+ " (sequence_no decimal, date_key int, activity_time_key int, ds_key int, ds_value decimal, tl_date_key int) row format delimited fields terimanted '~'";         string strmaintablesql = "create external table if not exists "+strtablename+" (sequence_no decimal, activity_time_key int, ds_key int, ds_value decimal, tl_date_key int) partitioned (date_key int) row format delimited fields terminated '~' location '/informatica/dwh/teradata/testtable'";         string strcreatesql = "create external table if not exists "+ strtablename + " (key int, value string) row format delimited fields terminated ','";         boolean res = stmt.execute(strcreatesql);         //show tables         string sql = "show tables '" + strtablename + "'";         resultset res1 = stmt.executequery(sql);          if (res1.next()){             system.out.println(res1.getstring(1));         }          sql = "describe "+ strtablename;         system.out.println("running: "+ sql);         res1 = stmt.executequery(sql);         while (res1.next()){             system.out.println(res1.getstring(1) + "\t" + res1.getstring(2));         }          // load data table         // note: filepath has local hive server         // note: /tmp/a.txt ctrl-a separated file 2 fields per line         string strfilepath = "/informatica/testing_hive_client_java.txt";         sql = "load data inpath '" + strfilepath + "' table " + strtablename;         system.out.println("running: " + sql);         res = stmt.execute(sql);          sql = "select count(1) "+ strtablename;         system.out.println("running: "+ sql);         res1 = stmt.executequery(sql);         while(res1.next()){             system.out.println(res1.getstring(1));         }        }// end of main   }// end of class

experts please pour in thoughts.

i able solve problem following code.

boolean reshivepropertytest = stmt                 .execute("set hive.exec.dynamic.partition = true");         reshivepropertytest = stmt                 .execute("set hive.exec.dynamic.partition.mode = nonstrict");

as code jdbc client code , execute go , execute in hive , worked me.
