Yes that was the problem.
I got confused between 2.0.1 and 2.1.0 after downloading the trunk source.

Thanks for the link.
I also found some useful infrastructure integration help
documents on your web pages.

Could you let the list know the ticket number, when you do? :)
Hello,
We have a column family which stores incoming requests, and we would like to
perform some analytics on that data using Hadoop. The analytic results should
be available pretty soon, not realtime, but within an hour or so.
So we store the current hour number (calculated from timestamp) a
I am working on a use case for Timeline series data. I have been told to
create 600 column families in Cassandra. Meaning for 10 minutes, I will be
having column families in Cassandra. Each second will have its own column
family, so till 10 minutes which is 600 second, I will be having 600 column
f
600 is probably doable but each CF takes up memory……PlayOrm goes with a
strategy that can virtualize CF's into one CF allowing less memory usage….we
have 80,000 virtual CF's in cassandra through playorm….you can copy playorm's
pattern if desired. But 600 is probably doable but high. 10,000 is
Hello Charles,
Thank you very much for your detailed upgrade report. It'll be very helpful
during our upgrade operation (even though we'll do a rolling production
upgrade).
I'll also share our findings during the upgrade here.
Cheers,

How do you install Cassandra on Ubuntu & later how do you upgrade the
installation on the node when an update has arrived ? Do you simply
download & replace the latest tar.gz, untar it to replace the older
cassandra files? How do you do it ? How does this upgrade process differ
for a major version
I don't know the full use case. However, for a generic time series scenario, we
can make the timestamp (may be unto second part) part of the key and write all
the data into the same CF(one CF for all data). Again, it may not make sense in
your case, given the full use case. Just my 2 cents.

I have to create Multiple Column Families in my keyspace. One way is to
create the column families one by one.. But in my case, I have around 100

This is the wrong object to use.
one overload of addColumn() accepts IColumn which is from
org.apache.cassanda.db . The thrift classes are only use for the thrift API.

If you can turn up logging to TRACE for
org.apache.cassandra.net.OutboundTcpConnection it will include the full error.

Could you explain that a little more?
You tried using the CqlStorage read with a CQL 3 table and it did not work ?

If reading all the request in an hour is something you do frequently than I
strongly recommend modelling that with another table.

The OP was using a Thrift table and CassandraStorage. I verified that the
problem does not exist with a CQL3 table and CqlStorage.

Thanks for the reply. Isn't the addColumn(IColumn col) method in the writer
private though? I know what to do now in order to construct a column with a
TTL now. Thanks.

Could you please clarify that:
1. when I upgrade to a newer version, would that retain my previous
configurations so that I don't need to configure everything again ?
2. would that smoothly replace the previous installation by itself ?
3. what's the way (kindly, if you can tell the command) to
