Subject Re: Bulk loader with Cassandra 1.2.5
Date Thu, 06 Jun 2013 22:53:31 GMT
Could it be because you are writing age as a long but have it defined as an integer in the
table definition?

Hi,
I am currently using Cassandra 1.2.5 on RHEL6 with Oracle JVM.
I want to try to build a bulk loader for stock prices that I have available in CSV format.
However, I have started exploring Cassandra from something easier, focussing on the example
available in the manual.

I cannot manage to have the bulk loader working as expected: once I create the sstables and
I import them with sstableloader, I cannot perform anymore "select * from users" in the CQL
console, or I get a java debug stack trace on the logfile and an rpc time out in the CQL console.

The code I am using is currently stored here: https://gist.github.com/davideanastasia/5720903

What am I doing wrong?

Thanks,
