Subject Re: Iterate through entire data set
Date Thu, 08 Apr 2010 18:44:10 GMT
I have two boxes.  One is a windows box running Cassandra .6, and the
other is an ubuntu box from which I'm trying to run the word count
program as in the readme.

The windows box seed is set to 127.0.0.1, and listen address to localhost.

The ubuntu box seed & listen is point to IP of the windows box.

from contrib/word_count:

~/dev/cassandra-0.6.0-rc1/contrib/word_count$ ant
Unable to locate tools.jar. Expected to find it in
/usr/lib/jvm/java-6-openjdk/lib/tools.jar

Sorry, I'm a bit new to this... help?
