load data into table hive - eclipse

Question

I'm trying to Configure Hive to Work with JDBC and I used this exemple on eclipse :
public class HiveJdbcClient {
private static String driverName = "org.apache.hadoop.hive.jdbc.HiveDriver";
/**
* #param args
* #throws SQLException
**/
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:hive://localhost:10000/default", "", "");
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 into table
// NOTE: filepath has to be local to the hive server
// NOTE: /tmp/test_hive_server.txt is a ctrl-A separated file with two fields per line
String filepath = "/tmp/test_hive_server.txt";
sql = "load data local inpath '" + filepath + "' into table " + tableName;
System.out.println("Running: " + sql);
res = stmt.executeQuery(sql);
// select * query
sql = "select * from " + 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) from " + tableName;
System.out.println("Running: " + sql);
res = stmt.executeQuery(sql);
while (res.next()){
System.out.println(res.getString(1));
}
}
}
I was able to create the table on hive but when I try to load data into the table an error appears . so my question is what should I put into "test_hive_server.txt" to make it work! Because I tried everything and each time I get the same error.
Thanks!
the error:
Exception in thread "main" java.sql.SQLException: org.apache.thrift.TApplicationException: Internal error processing execute
at org.apache.hadoop.hive.jdbc.HiveStatement.executeQuery(HiveStatement.java:196)

Answer 1

I found the answer by myself actually the :
ROW FORMAT DELIMITED FIELDS TERMINATED BY ' ';
determinate the format of the rows in the "file.txt" that we are going to load in the table and Hive’s default record and field delimiters list is :
\n
^A
^B
^C
press ^V^A could insert a ^A in Vim.
or you can just do:
create table tableName (key int, value string) ROW FORMAT DELIMITED FIELDS TERMINATED BY ' ';
and the 'file.txt' should be like this:
value1 value2
value3 value4
in this example value1 and value3 represent the key
and value4 and value5 represent the value
