I've just hit the seg fault as well, using OpenJDK on a Ubuntu box. The fix is to change the stack size as described here: http://stackoverflow.com/a/14447535/1852070
Apparently this fix may be required for both Oracle Java and OpenJDK. Is there a strict requirement on Oracle Java for any other part of OAE? cheers, Steve On Thu, Jul 25, 2013 at 3:28 AM, Branden Visser <mrvis...@gmail.com> wrote: > Ok, segmentation fault, we're getting somewhere :) > > > http://stackoverflow.com/questions/11901421/cannot-start-cassandra-db-using-bin-cassandra > > It's likely switching to Oracle Java 6 will fix the problem on its > own, and should give a more common environment in which to run > Cassandra. > > Let me know how that goes! > > Cheers, > Branden > > On Wed, Jul 24, 2013 at 1:12 PM, David Torres <david.tor...@renuda.com> > wrote: > > apache-cassandra-1.2.6/bin/cassandra, not 1.2.2, right? > > > > Yes, 1.2.6.
