Ok. I am able to understand the problem now. Issue is:
If i create a column family altercations as:
**********************************************************************************************************8
CREATE TABLE altercations (
instigator text,
started_at timestamp,
ships_destroyed int,
energy_used float,
alliance_involvement boolean,
PRIMARY KEY (instigator,started_at,ships_destroyed)
);
/
INSERT INTO altercations (instigator, started_at, ships_destroyed,
energy_used, alliance_involvement)
VALUES ('Jayne Cobb', '2012-07-23', 2, 4.6, 'false');
*********************************************************************************************************************
It works!
But if i create a column family with compound primary key with 2 composite
column as:
*********************************************************************************************************************
CREATE TABLE altercations (
instigator text,
started_at timestamp,
ships_destroyed int,
energy_used float,
alliance_involvement boolean,
PRIMARY KEY (instigator,started_at)
);
*********************************************************************************************************************
and Then drop this column family:
*********************************************************************************************************************
drop columnfamily altercations;
*********************************************************************************************************************
and then try to create same one with primary compound key with 3 composite
column:
*********************************************************************************************************************
CREATE TABLE altercations (
instigator text,
started_at timestamp,
ships_destroyed int,
energy_used float,
alliance_involvement boolean,
PRIMARY KEY (instigator,started_at,ships_destroyed)
);
*********************************************************************************************************************
it gives me error: "TSocket read 0 bytes"
Rest, as no column family is created, so nothing onwards will work.
Is this an issue?

Works for me on latest 1.1 in cql3 mode. cql2 mode gives a parse error.
