Hello Joseph, CASSANDRA-7910 is fixed for Cassandra 2.1.3, but it still needs a fix driver-side: JAVA-420 <https://datastax-oss.atlassian.net/browse/JAVA-420>. Until this is not solved, the workaround (and the best practice) is to avoid using "SELECT *" statements and explicitly name the columns you need.
Hope that helps, Alexandre On Fri, Aug 28, 2015 at 4:58 AM joseph gao <gaojf.bok...@gmail.com> wrote: > if already fixed, my use case is wrong.
