Hi Aaron, Thanks for your response. I didn't make any change to the code when I got that exception. I just ran the example as is after I cloned the repo from github.
I did a git pull today on cassandra-2.0 branch, built via ant and re-ran the example and now I am not getting the error from before but I am now getting the following error as shown in this gist https://gist.github.com/parth-patil/7864738 On Sun, Dec 8, 2013 at 11:30 AM, Aaron Morton <aa...@thelastpickle.com>wrote: > InvalidRequestException(why:consistency level LOCAL_ONE not compatible > with replication strategy (org.apache.cassandra.locator.SimpleStrategy)) at > > The LOCAL_ONE consistency level can only be used with the > NetworkTopologyStrategy. > > I had a quick look and the code does not use LOCAL_ONE, did you make a > change? > > Cheers > > ----------------- > Aaron Morton > New Zealand > @aaronmorton > > Co-Founder & Principal Consultant > Apache Cassandra Consulting > http://www.thelastpickle.com > > On 3/12/2013, at 10:03 pm, Parth Patil <parthpa...@gmail.com> wrote: > > Hi, > I am new to Cassandra and I am exploring the Hadoop integration > (MapReduce) provided by Cassandra. > > I am trying to run the hadoop examples provided in the cassandra's repo > under examples/hadoop_cql3_word_count.
