Repeatedly getting this error:

2011-02-11 00:05:11,688 WARN org.apache.hadoop.ipc.HBaseServer: IPC Server listener on 60000: readAndProcess threw exception java.io.EOFException. Count of bytes read: 0
java.io.EOFException
        at java.io.DataInputStream.readFully(DataInputStream.java:180)
...


Initialization looks ok, otherwise (connects to zookeeper, sets self up as master, starts executor service, all that).


My classpath (split on ':' for readability):

hbase.jar is a symlink to hbase-0.90:

/usr/local/hbase -> /usr/local/hbase-0.90.0

/usr/local/hbase/hbase.jar -> /usr/local/hbase/hbase-0.90.0.jar
