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

  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 
org.apache.thrift.protocol.TBinaryProtocol.readMessageBegin(TBinaryProtocol.java:203)
     at 
org.apache.hadoop.hive.service.ThriftHive$Client.recv_execute(ThriftHive.java:72)
     at 
org.apache.hadoop.hive.service.ThriftHive$Client.execute(ThriftHive.java:57)
     at com.tubemogul.rtb.datastore.HiveDAO.testThrift(HiveDAO.java:59)
     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

Hi,

can you try with just the JDBC client first? (you shouldn't need to use any
of those TTransport code).

make sure you have hive-jdbc-0.7.0.jar and libfb303.jar in your classpath.
it might also help if you post the command you run to start Hive Server and
the server logs.

Thanks,
T

Sorry I rexplain my situation.

I try to connect from an Java app to a Hive server.

I start with the JDBC solution and I found the Java Heap Space problem. After that, I try with the Thrift client and I had also the same problem.

After adding more memory I have this problem exception in the both case :

sorry I am a little bit confused - so are you trying to connect to Hive
server via a JDBC client *or* a Thrift client?

were you able to run the above JDBC client code without any problem?

Cheers,
Todd

  First of all, thanks for you answer.

I have exactly the same JDBC code. After increase the heap size, it's 
getting better but I have now a new error :

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

Posted by Todd Lee <ro...@gmail.com>.
to use Hive with JDBC, you should probably do something like this,

Connection con =
DriverManager.getConnection("jdbc:hive://localhost:10000/default", "", "");
Statement stmt = con.createStatement();
String sql = "show tables;"
ResultSet res = stmt.executeQuery(sql);
...

for OOM error, try increase the heap size in Hadoop by uncommenting this
line in hadoop-env.sh

export HADOOP_HEAPSIZE=2000
