awesome!
this week I am (finally) getting cassandra (0.8) going for existing projects
we have in production.

was thinking maybe I could start to help out but I am not sure that is the
best starting point though it is a

Hi all
after upgrading to 0.7 we have a small problem with dynamic snitch:
we have rf=3, quorum read/write and read repair prop set to 0. Thus cassandra
always shortcuts reads to only 2 hosts.
Problem is that one of our nodes get ignored unless using a little patch and
initialize the scores.
(I presume there is some way of representing :, like \:?)
Well no, not yet, but we'll try to figure something I guess (we'll have the
problem with CASSANDRA-2474 I think so we'll probably use the same
solution).
But let's keep in mind this is unreleased code at this point. And let me
also add
I use a custom comparator class. So I think there is a high chance that I do
something wrong there. I was thinking that the stack trace could give a clue
and help me on the way, maybe because some already got the same error.
Anyway, here is some more information you requested.

I'm not a php type person, but I can help a little with thrift.
Install thrift 0.6 and then run this in the interface/ directory of the
cassandra source...
thrift --gen php cassandra.thrift
You should end up with the interface/gen-php/
Hope that helps.

First thing to do would be to update to 0.7.5.
The assertionError you're running into is a assertion where we check
if a skipBytes
did skip all the bytes we had ask him to. As it turns out, the spec
for skipBytes authorize
it to not skip all the bytes asked even with no good reason. I'm
pretty
Ok, I will do that (next test will be done on some linux boxes being installed
now, but at this time I need to gone with the current windows setup).
Question : Can I use the 0.7.4 data files as is? Do I need to backup the
datafiles in order to be able to get back to the 0.7.4 version if needed?

Seems like the AbstractType class has changed going from 0.7.4 to 0.7.5.
It is now required to implement a compose and decompose method. Already did
that, and it starts up with the 0.7.5 code using the 0.7.4 data and
configuration (using a smaller extra test database)
Below I made a sample
I guess otherwise it NPEs?
Looks like a bug, can you open a ticket?

Nothing comes to mind.
I'd start by using sstable2json to see if the missing rows are in the
main data CF -- i.e., are they just unindexed, or are they missing
completely?

Hi All,
I was diagnosing high CPU usage on my Cassandra 0.6.3.Then i came
across Cassandra wiki link which suggested following.
To lower compaction priority (thus reducing its impact on the rest of
the system, and making it take longer), add these options to

Here is the snapshot of the logs from one of the machine between the time
when I mailed to when it finally started to look at the commitlogs. At the
end you can see that it is discarding obsolete commitlogs. Not sure what
that means.

You've had people on this list tell you you should upgrade off such an
old release at least twice already this month.
The reason we do this is, the odds are good that the answer is
someone else ran into that problem a year ago and it got fixed.

Looking at the code the exception below can happen if the ip address cannot be
found in the topology and there is no default set.
To test this theory set the logging the DEBUG and look for a log message from
the PropertyFileSnitch that says
Could not find end point information for {}, will use
Use the plain text password via the cli, the server will make a hash and
compare it to the one in the file.
wrt SHA-2 I'm not a security guy but MD5 is probably good enough for the
problem of storing passwords in plain text in a file.
Hope that helps.

Those messages are ok to ignore. It's basically deleting the files that are
already flused as SSTables.
Which version are you running?
Have you tried restarting the node?
Pick one node and send ls -ltr output also the complete log files since
your last restart from the same node. I looked at
Hey Aaron,
Unfortunately it fails with plaintext password also:

I am pleased to announce the release of Apache Cassandra 0.8.0 rc1.
The final release is upon us so if you're planning to give us a hand
with testing, now is the time!
As always, be sure to have a look at the changelog[1] and release
notes[2]. Report any problems you find[3], and if you have

Opps, my bad... please ignore the email below. It actually works with the
