We're running into a problem where things are fine if our client runs
single threaded but gets TransportException if we use multiple threads.
The datastax driver gets an NIO checkBounds error.
Here is a link to a stack overflow question we found that describes the
problem we're seeing. This

Hi Stan,
Put some monitoring on this.
Thanks everyone for the feedback. So some additional details...
1. Definitely using Oracle JDK (1.7.0_71-b14)
2. Yes, the segfaulting does go away after a restart

4. We are seeing many GC pauses that take a long time, as in over 2 seconds

In the logging configuration that ships with the cassandra distribution
(log4j-server.properties in 2.0, and logback.xml in 2.1), the rolling file
appender is configured to print the file name and the line number of each

I have a 30+ node cluster that is under heavy read and write load. Based on
the fact that we never delete data, and all data is inserted with TTLs and is
somewhat temporal if not upserted, and we are fine with the consistency of one

Hey all,
I'd like to connect my cassandra 2.1.2 cluster to hadoop to have it
process the data. Are there any good tutorials you can recommend on how to

hadoop name node is CentOS 7.
Thanks
Tim
