Zookeeper returns wrong host port for HMaster
// I have some sample code (to list hbase tables) that runs on the
zookeeper / HMaster node , see below
import java.io.IOException;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.HTableDescriptor;
import org.apache.hadoop.hbase.client.HBaseAdmin;
public class HBaseAdminExample {
public static void main(String[] args) throws IOException {
Configuration config = HBaseConfiguration.create();
HBaseAdmin hbaseAdmin = new HBaseAdmin(config);
//List<String> outputList = new ArrayList<String>();
for (HTableDescriptor htd: hbaseAdmin.listTables()) {
//outputList.add(htd.getNameAsString());
System.out.println("table is: " + htd.getNameAsString());
}
}
}
// The outputs is this:

Any ideas why zookeeper seems to be returning :
� 3105@namenodeone.myclusternamenodeone,60000,1329676853513 as its HMaster
host and port instead of namenodeone:45134 (for example)
Thank you,

Wipe your zk. It looks like you were messing w/ hbase 0.92 and then
went back to 0.90? Is that so Ryan?

Yes St.Ack,
Client side was using hbase-0.90.5 libs. HBase server was using 0.92.0.
Of course I saw this but it didnt click at the time... Thanks St.Ack!

And what you are seeing above is a few bytes that hbase now writes as
sequence number whenever it puts an edit into zk followed by the new
format we store names to zk as which is name, port, and startcode.
