Confusing connection issue with client
Hey all,
I'm just starting with both Hadoop and HBase. I've created a 3-node cluster
- 1 master and 2 slaves. I've had some fun in the shell, where everything
works as expected, and look forward to wrapping my head around the java
client interface. Using the wiki FAQ as a guide, I wrote my first unit
test, but it's throwing an exception I can't explain:
08/02/03 00:12:46 INFO hbase.HConnectionManager$TableServers: Attempt 0 of 5
failed with <org.apache.hadoop.ipc.RemoteException: java.io.IOException:
Unknown protocol to name node: org.apache.hadoop.hbase.HMasterInterface
at org.apache.hadoop.dfs.NameNode.getProtocolVersion(NameNode.java:79)
at jrockit.reflect.VirtualNativeMethodInvoker.invoke(Ljava.lang.Object;[
Ljava.lang.Object;)Ljava.lang.Object;(Unknown Source)
at java.lang.reflect.Method.invoke(Ljava.lang.Object;[Ljava.lang.Object;I)Ljava.lang.Object;(Unknown
Source)
at org.apache.hadoop.ipc.RPC$Server.call(RPC.java:379)
at org.apache.hadoop.ipc.Server$Handler.run(Server.java:596)
My hbase-site.xml and unit test source are below. I haven't altered
hbase-default. I feel like I must be missing something obvious. Any ideas?
public void testJustGettingStarted() throws Exception {
Configuration conf = new HBaseConfiguration();
HBaseAdmin admin = new HBaseAdmin(conf);
HTableDescriptor[] tables = admin.listTables();
for ( HTableDescriptor table : tables ) {
LOG.info( table.getName() );
}
HTable newA = new HTable(conf, new Text("test") );
Text row = new Text("testRow");
// Now fetch the content just added
byte data[] = newA.get(row, new Text("test:test") );
LOG.info( data );
}

Update: I grabbed 0.16.1, deployed everything as it had been before and the
unit test now runs perfectly. Thanks again, Jean-Daniel. Now for the real
fun...

No problem, I ran into the same kind of problem lately but using the latest
code available and it was something like my port wasn't open but, as it was
running inside a VMware (I don't want to mess with my 12 nodes cluster too
much), I resorted to running the code inside the vm.
But for your case, I would first suggest using the latest code on your
cluster and remote client because 0.15.x isn't really supported for HBase
(read http://wiki.apache.org/hadoop/Hbase/Plan-0.17). I may also suggest
using the all new HBase email list :
hbase-user-subscribe@hadoop.apache.org
Not sure if it will fix your problem, just a guess ;)

Thanks for the quick reply, Jean-Daniel.
I'm running the test remotely from the cluster. I used the 0.15.3 release
for all the machines in the cluster and but built the local code from
branch-0.15. To be safe, I just reran the test using jars from the
0.15.3download but received the same error.

Hi,
I guess you're using the SVN version. Are you running your test on the
master node or remotely?
