Re: monitoring read and write problems via log file?
I was told by a colleague that read and write problems in Cassandra can be detected by monitoring a Cassandra log file. What do you mean by problem? If you mean something like a hard I/O error or corruption causing an internal error, you should get an exception of some kind in the system log (typically /var/log/cassandra/output.log or similar, unless otherwise configured). -- / Peter Schuller

Re: (newbie) ColumnFamilyOutputFormat only writes one column (per key)
I then went to write a m/r job that deserialises the thrift objects and aggregates the data accordingly into a new column family. But what i've found is that ColumnFamilyOutputFormat will only write out one column per key. I've entered a bug for this: https://issues.apache.org/jira/browse/CASSANDRA-1774 ~mck signature.asc Description: This is a digitally signed message part

Re: [RELEASE] 0.7.0 rc1
The corresponding RPMs can be found on http://rpm.riptano.com Instructions for adding the riptano repository can be found here: http://www.riptano.com/blog/announcing-rpms-cassandra ***This is not an upgrade from the 0.6.x RPMs. See below for details Notes: - if you have 0.6.x RPMs installed, do not even attempt this on a production cluster until you fully understand the ramifications of upgrading from 0.6 to 0.7 - the name for the 0.7.x series will be cassandra07 to avoid conflicts with upgrade/update from 0.6.x - the RPM itself conflicts with the 0.6 package so you must uninstall the 0.6 RPM first (it will leave your data and existing configurations intact) * this may change in the future but requires modifications to some of the scripts in contrib - you must load/convert your schema to yaml yourself. See NEWS.txt in the release (http://goo.gl/cCabD) for details For any feedback or issues with the RPMs, please let me know directly.
