Description

One of our application bug inserted blank key into cluster causing assertion error on key. After checking the root cause, I found it is the bug with CQL and reproducible. Client cassandra-node and cqlsh-1.0.6.
Blank key only work when one column provided.

{}
cqlsh> insert into login (KEY,email)values('','');
cqlsh> select * from login;
u'' | u'email',u''
cqlsh> insert into login (KEY,email,verified)values('','','');
Request did not complete within rpc_timeout.
