Hello Everyone,
I got some exceptions when I run the following code:
HBaseConfiguration config = new HBaseConfiguration();
HTable table = null;
ResultScanner scanner = null;
try {
table = new HTable(config, tableName);
Scan s = new Scan();
s.addFamily(Bytes.toBytes(ColumnFamily));
scanner = table.getScanner(s);
... ...
And the exceptions are:
java.io.IOException: Call to /192.168.33.6:60020 failed on local exception:
java.io.EOFException
java.io.IOException: Call to /192.168.33.6:60020 failed on local exception:

I think my codes are really simple, can you tell why these exception
were thrown?
Thanks a lot,
