Silly question -- but does hive/pig hadoop etc work with cassandra 1.1.8? Or only with 1.2? We are using astyanax library, which seems to fail horribly on 1.2, so we're still on 1.1.8. But we're just starting out with this and i'm still debating between cassandra and hbase. So I just want to know if there is a limitation here or not, as I have no idea when 1.2 support will exist in astyanax.
That said, are there other java (scala) libraries that people use to connect to cassandra that support 1.2? -James- On Thu, Jan 17, 2013 at 8:30 AM, <cscetbon....@orange.com> wrote: > Ok, I understand that I need to manage both cassandra and hadoop components > and that pig will use hadoop components to launch its tasks which will use > Cassandra as the Storage engine. > > Thanks > -- > Cyril SCETBON > > On Jan 17, 2013, at 4:03 PM, James Schappet <jschap...@gmail.com> wrote: > > This really depends on how you design your Hadoop Cluster.
