Thirft + JDBC : java.lang.OutOfMemoryError: Java heap space

[Francois LAGIER]

 Hello everybody,

I just start working on HIVE so maybe my question will be stupid but for 
the moment I am completely stuck so ...

I try to create a Java app, and try to launch some query on my Hive Server.
After reading the wiki, I try with JDBC and Thrift.

For the moment, I just try to connect to the server, to launch a very 
basic query ("Show tables") and display the result in my console.
In the both case, JDBC and Thrift, I have always the same result :

Exception in thread "ImportDataModule" java.lang.OutOfMemoryError: Java 
heap space
    at 
org.apache.thrift.protocol.TBinaryProtocol.readStringBody(TBinaryProtocol.java:296)

    at 
com.tubemogul.rtb.daemon.ImportDataThread.run(ImportDataThread.java:54)
    at java.lang.Thread.run(Thread.java:619)

And this is my function :

TTransport transport;
try {
    transport = new TSocket("my-server", 9999);
    TProtocol protocol = new TBinaryProtocol(transport);
    HiveClient client = new HiveClient(protocol);
    transport.open();
    client.execute("SHOW TABLES");
    //List<String> a = client.fetchAll();
    transport.close();
} catch (HiveServerException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (TException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}


Now, I really hope one of you already have this problem and already fix it.
I am sorry if you already talk about that in one of your email but I 
didn't find something to fix that,

Thanks in advance,

Francois
