Sorry, I'm not following your example.
Could you describe the request you sent, what you expected to get back and what
you actually got back. Are you able to reproduce the fault in a clean install,
e.g. load this data, run these commands and then it goes bang ?

I *think* that message is just from when the connection is closed.
Sorry this is a hard one to help with, as it's more than likely something to do
with your client app.
Some guessing...
Everything is working if you do not use the authenticator ?
Can you inspect the ports on the server and
just test...
Hi Tyler, insert does not seem to have a have a return value.
However a stranger thing has now happened - the problem has just gone away in
the last hour. Hard to believe nothing changed I am sure!
I have tried simulating timestamps from earlier when it wasn't working and
still cannot get it
I was trying to get Cassandra 0.6.8 (latest stable release) going for
the first time and my attempts at getting the example code to run caused
Cassandra to die with out a JavaMemoryError just by connecting
cassandra-cli to cassandra.

Looking at the thrift code it is allocating arrays based on lengths read of
the wire, without adequate validation of the length. This allows client
errors to crash the server :(
This is fixed with latest cassandra and current versions of thrift. I
don't remember whether it was a thrift bug in
Hi Aaron,
Thanks for the help..
If I don't use the Authenticator, and keep it at AllowAll it will work
find..
I tried provide an invalid password but it behaved the same...
Here is what i am doing:
MapString, String creds = new HashMapString, String();
creds.put(username, pwd);
UPDATE: Solved
After digging deeper I realised that I had patched fastbinary incorrectly for
compiling under visual studio on windows and was left with the wrong endian
define.
As the app often worked it never crossed my mind to check this out!
Many thanks Tyler for all your suggestions.

please explain the difference between load (from nodetool) and whats actually
stored on disk? Sometimes these number mirror each other and sometimes the disk
usage is up to 2x the load reported. as you can see below...

Hello all, I have a very strange issue where I updated a column value with the
cassandra-cli command line interface and I can see with the cli tool that the
value is there and correct. When I query the same column via PHP and Thrift no
value is returned. I can make updates to any other column
What Cassandra version? What PHP client? How are you doing the insert with
the CLI? What is your query with PHP?

Did you post your patch to the Thrift project?

I believe the map of credentials should be
creds.put(username, your_username);
creds.put(password, your_password);
So you have two entries in the map, one for user and one for password. No
idea why that call would be hanging though.

Actually it turns out there is a submitted patch for this already from January
2009 but it was never accepted due to a complaint about an unnecessary cast! I
have modified and resubmitted the patch.

Hi:
I get column value from cassandra 0.6 as (column=2WwADF3V3A0A5b,
value=1WwACGIHDn0A45, timestamp=1286949750195000)) format
but get (column=2WwADF3V3A0A5b, value=3157774143474948446e30413435,
timestamp=1286949750195000)) from 0.7 beta3
how can I get the column value in human-readable
I found the reason (in the view of client side).
I used unit test of my DAO class. the test class inserted test row and
columns before doing test, and then do test, finally delete inserted
columns after test.
The test was succeeded at first. When I do that test again, the test
code attempt to
Thanks, its working now...

Hi,
Our team decided to use Cassandra as storage solution to a dataset.
I am very new to the NoSQL world and Cassandra so I am hoping to get
some help from the community: The dataset is pretty simple, we have
for each key a number of columns with values. Each day we compute a
new version of this
Not sure how you are reading the data, but try setting the comparator to ASCII
or similar. This will tell Cassandra that the column names are strings.

There´s a simple comparison that helped me a lot taking my first steps with
cassandra:
keyspace = database
CF = table

And this one: http://arin.me/blog/wtf-is-a-supercolumn-cassandra-data-model
Btw, love the new secondary indexes in cassandra 0.7, this saves a lot of
time and work! But
