Subject A few issues with the latest code
Date Sun, 28 Jun 2009 19:58:51 GMT
Jonathan,

I have checked out the latest version of Cassandra and noticed a few things
not working.

Here's the sequence of steps I conducted:

1. Start up cassandra successfully (listener bind to 192.168.216.162)

ichang@ubuntu:~/workspace/Cassandra2$ bin/cassandra
ichang@ubuntu:~/workspace/Cassandra2$ Listening for transport dt_socket at
address: 8888
DEBUG - Loading settings from bin/../conf/storage-conf.xml
DEBUG - adding Super1 as 0

DEBUG - adding StandardByTime1 as 3
DEBUG - adding LocationInfo as 4
DEBUG - adding HintsColumnFamily as 5
DEBUG - Starting to listen on 192.168.216.162:7001

2. http://192.168.216.162:7002 NOT working, older versions of code is
working

3. Smoke test through cassandra-cli is successful, but the syntax get
Table1.Standard1['jsmith'] isn't working, the system.log indicated the error

cassandra> get Table1.Standard1['jsmith']

So smoke test using cassandra-cli works (except for the wildcard query get
Table1.Standard1['jsmith'] i), but http://192.168.216.162:7002 isn't working
anymore.  I am wondering if the port has changed in the latest code.
