I downloaded cassendra 0.6.5 and ran it, got this error:

bin/cassandra -f
 INFO 16:46:06,198 JNA not found. Native methods will be disabled.
 INFO 16:46:06,875 DiskAccessMode 'auto' determined to be mmap, indexAccessMode is mmap

is this an issue?

When I tried to run cassandra cli from the example, I got the following errors:

cassandra> use Keyspace1 sc 'blah$'
line 1:0 no viable alternative at input 'use'
Invalid Statement (Type: 0)
cassandra> set Standard2['jsmith']['first'] = 'John';
line 1:13 mismatched input '[' expecting DOT

is this a setup issue?
