Hi,
I've a 4 node cluster of cassandra 0.8.7 (upgraded just recently from
0.7.8). Upgrade went smothly, no problem with the data.
Problem are my MapReduce tasks. The all report:
java.io.IOException: InvalidRequestException(why:Column timestamp is required)
at
org.apache.cassandra.hadoop
As usually happen, I've found the problem just after I sent the
question. I have to use setters for setting values to thrift.*
classes.
So instead of:
Deletion d = new Deletion();
d.timestamp = 1;
use:
Deletion d = new Deletion();
d.setTimestamp(1);
etc.
Regards,
Patrik
Hello,
SimpleAuthenticator & SimpleAuthorization just disappear in release 1.0.0...
Will this stay like this or is it a release bug ?
Thanks,

Hello Aaron,
I happen to have 48GB on each machines I use in the cluster. Can I
assume that I can't really use all of this memory productively? Do you
have any suggestion related to that? Can I run more than one instance on
Cassandra on the same box (using different ports) to take advantage of
I have noticed this too. Apparently it is a thrift code generation thing.

Hi all.
I am using cassandra 1.0.0.
I created a keyspace with all the column family definitions at runtime and
it works fine until I stop and then restart the cassandra server.
During it's startup I see this error in the cassandra log :
ERROR 16:22:16,977 Exception encountered during startup

Hi,
I installed Cassandra 0.8.7 on a single machine having 16GB RAM.
Testing performance using stress tool. Noticed it creates 2 standard
column families and 2 super column families with the default settings.
I want to test for multiple column families. Is there any way to test it
using this
I have been playing around with Cassandra 1.0.0 in our test environment it
seems pretty sweet so far. I have however come across what appears to be a
bug tracking node load. I have enabled compression and levelled compaction
on all CFs (scrub + snapshot deletion) and the nodes have been operating
Are you using cassandra's caching? If you are then you will need to play
around with the RAM setting to find a sweet spot. A low hit rate on the
cache (which is counter productive anyway) will cause more GC. A high hit
rate, less GC.
If you are not caching, no need to use a large heap as the OS

We are running a 8 node cassandra 1.0 cluster. We are seeing this
exception quite often. Any idea how to debug this issue?

I have a vague memory of there been a bug about this in the past.

Solr can use a dynamic schema…
https://github.com/apache/lucene-solr/blob/trunk/solr/example/solr/conf/schema.xml#L538
But you may still want to define a schema so you can adjust the index and query
time processing/typing of the field values.

It's unlikely that HH is the issue. (Disclaimer, am not familiar with HH in
1.0, i know it's changes a bit)
Take a look at the TP Stats, what's happening ?

Looks like a bug, patch is here
https://issues.apache.org/jira/browse/CASSANDRA-3391
Until it is fixed avoid using CompositeType in the key_validator_class and blow
away the Schema and Migrations SSTables.

That looks to me like it's reporting uncompressed size as the load.
Should be fixed in the 1.0 branch for 1.0.1.

The stress tool doesn't support doing multi-CF batches out of the box. Of
course you're free to extend it any way you like to more accurately simulate
your workload. (That's one reason we've kept stress.py around -- it's less
code to customize, than the Java version.)
