Subject Re: [jira] [Commented] (GORA-22) Upgrade cassandra backend to cassandra 0.7
Date Fri, 22 Jul 2011 23:08:08 GMT
Hi,

Sorry I have committed my changes before I had the go ahead of the
other peers. I am still learning the opensource etiquette. I thought
it was fine to replace the code since I believe the Cassandra part was
broken. I personnally never managed to use the code "as is". It was
mentioned to me the entire backend needed to be rewritten:
See Julien's comment in this page:
http://techvineyard.blogspot.com/2011/01/trying-nutch-20-hbase-storage.html:

"The Cassandra backend in GORA is in need of serious work and is not
considered fully functional, IIRC it is not thread safe. There has
been a new release of Cassandra in the meantime and I am pretty sure
that it would be quicker to simply write a new backend for GORA based
on the latest release..."

Now we have 2 options:
- revert the modifications and go back to a broken state
- test the new version and iterate from there. I'm sure it's not
perfect but at least we have a seemingly working state to start with.

Sorry for the bad surprise.

What does your patch do that improves or adds to it? Would be great to explain for the benefit
of others watching.
