Used to manage/develop for cassandra 1.0.8 for quite sometime. Although 1.0
was rocking stable but we encountered various problems as load per node

if you are just started, you could use this one node for your learning by
installing multiple instances for experiments or development purposes only.

Hey Robert, you might want to start by looking into the statistics of

Rob, the cluster now upgraded to cassandra 1.0.12 (default hd version,
in Descriptor.java) and I ensure all sstables in current cluster are

cassandra 1.1.12 , the sstable is version hf version. so i guess,

Hello,
Reading this documentation http://www.datastax.com/docs/1.1/install/upgrading
If you are upgrading to Cassandra 1.1.9 from a version earlier than
1.1.7, all nodes must be upgraded before any streaming can take place.
Until you upgrade all nodes, you cannot add version 1.1.7 nodes or
later

Hi, our cassandra node using java 7 update 72 and we ran jstat on one of
the node, and notice some strange behaviour as indicated by output below.
any idea why when eden space stay the same for few seconds like 100% and
18.02% for few seconds? we suspect such "stalling" cause timeout to our
cluster

Check if you have the cqlshlib installed? For debian, it is located
at /usr/share/pyshared/cqlshlib

You could probably use one of these
nodetool getendpoints- Print the end points that
owns the key
using cqlsh and desc keyspace;

I had the same version upgrade path you had but using debian binary
package. Looks like it could be the java cannot find the main class, try
find out by executing ps and grep for the cassandra process, then it should
show a lot of classpath, check if you apache-cassandra-2.0.2.jar in the
classpath.
Sorry, I have no knowledge on Node.js, probably someone else might know.

Nature of issue CASSANDRA-4573 compare to "Read an invalid frame size of
0." looks different, nevertheless if someone can test the issue fix would
include invalid frame size.. would be awesome!

you can try nodetool scrub. if it does not work, try repair then cleanup.

Would it possible to delete this row and reinsert this row? By the way, how
large is that one row?

Here is a list of keywords and whether or not the words are reserved. A
reserved keyword cannot be used as an identifier unless you enclose the
word in double quotation marks. Non-reserved keywords have a specific
meaning in certain context but can be used as an identifier outside this
context.

Probably also ensure port 7000 for the nodes to be reachable between nodes.

Shouldn't be difficult to google what you want for starter... but here are

Hi, you can use cassandra-cli / cqlsh with option --file to load the ddl.
or cassandra client..http://wiki.apache.org/cassandra/ClientOptions

This happened sometime ago, but for the sake of helping others if they
encounter,
each column family has a row cache provider, you can read into the schema,
for example :
...
and row_cache_provider = 'SerializingCacheProvider'
...
it cannot start the cache provider for a reason and as a result,
You need an equal operator in your query. For instance, SELECT * FROM
users WHERE country = 'malaysia' age > 20
