Hi!
I'm trying to get Casandra running on Ubuntu 8.04.2 LTS (hardy). I've got it
installed but when I try and run it with "casandra -f" I get some lines of
debug info then the following error twice in a row:
ERROR - Exception encountered during startup.

Hi ML.
this sounds more like a job for SOLR, but if you want to do this with
cassandra,
you should look at Jake's Lucandra http://github.com/tjake/Lucandra
you should also look at

I didn't see any C# libraries that generate type 1 UUIDs. You might

I think I am reading this right, basically you want to query for a
word and find all of the documents that contain it? While there may be
a better way to do this, the way the people at Facebook do it is with
supercolumns. Inside the supercolumn column family they have columns
for every word, such a

Cassandra server use UUID version 1. Maybe the uuidgen.exe does not

MSP going up and down doesn't seem like a big deal. is load
abnormally high on that box? did you check the log? (maybe it is
sending hinted data to the node that was down 12h?)
"loads of timeouts" isn't much to go on, again, what is your telemetry
showing? high load? large work queues?

So it seems to correlate with writes, the machines with pending tasks
in their MESSAGE-SERIALIZER-POOL also have a high number of write counts,
so my keyspace is probably out of balance. Hopefully the tools available
in 0.5 will allow me to move keys around to make things a little more
evenly dist
So I restarted the node with the large number of ROW-READ-STAGE pending
tasks, the timeouts are still occuring somewhat randomly, and now
MESSAGE-SERIALIZER-POOL seems to be growing on one of the nodes

Hey,
I've been reading up on the Cassandra data model a bit, and would like to
get some input from this forum on different techniques for a particular
problem.
Assume I need to index millions of text docs (e.g. research papers), and
allow the ability to query them by a given word inside or aroun
if the queued reads is increasing then you're going to OOM eventually,
and it will probably freeze (to the clients' perspective) first while
it desperately tries to GC enough to continue. i would restart the
affected nodes.

Good point although there has been very recent work integrating solr with
katta so you can have your cake and eat it too:

Thanks Jonathan.
I tried 0.5 rc2, 0.5 rc3 and the error still exists.

Dear Mr Jonathan,
With the larger sstable, I don't have any problem. So I think that the error
does not related to the heap size. And my data model does not use
SuperColumn, so I think the the number of columns in row is not the
problem.
I have tried to delete error row and accept data lost.
On
+1 from me, for sure.

I can give you a few more data points. For one of my last projects, I
built the search index of one of the largest IM aggregators. I got
around 2.5k chat msg/s, keeping 400M messages in my index.
I looked at Solr and while it is very convenient/luxurious, there was
no way in hell I could scale it
