Hi,
I have been running Cassandra 1.0.7 and in the log file I see the log saying
" Finished hinted handoff of 0 rows to endpoint /{ipaddress}"
The above issue can be reproduced by the following steps,
1. Start a cluster with 2 node, suppose node1 and node2
2. Create a keyspace with rf=2, create
Hi,
I can see some strange behaviour on my test cluster and in production.
Both running cassandra 0.8.10. Strange is that when I compile my
mapreduce job against cassandra-all 0.8.7 everything is ok, but if I
use higher version I get quite a lots of TimedOutException.
java.lang.RuntimeException:
Some more info, running the cluster with debug enabled shows this error:

Hi Aaron and Martin,
Sorry about my previous reply, I thought you wanted to process only all the
row keys in CF.
I have a similar issue as Martin because I see myself being forced to hit
more than a million rows with a query (I only get a few columns from every
row). Aaron, we've talked about thi

Hello everyone,
I'm battling with this contraint that I have: I need to regularly ship out
timeseries data from a Cassandra cluster that sits within an enclosed
network, outside of the network.
I tried to select all the data within a certian time window, writing to a
file, and then copying the fi
Check out the troubleshooting section of the hadoop support - we ran into the
same thing and tried to update that with some info on how to get around it:

Hi Jeremy,
I've seen the page and tried the values but to no help.
Here goes tcpdump of one failed TCP connection:

Hi everyone,
what do I use in order to insert bytes instead of characters into a
column, using CQL with the Thrift-client?
It's a special case of a single sstable existing for hints:

Assuming the type is 'blob' (bytes), use hex encoding.

That works - but only for static columns. How do I use this with
dynamic columns? And how can I specify column-names that are bytes
(rather than characters) themselves in CQL?

Yes, but why? Is it because composite columns effectively replace and

Thank you - that works perfectly!
One final question, is this in the docs somewhere - or where should I
look into in the future for questions like these? Google doesn't seem
to be much help since it mostly refers to the docs by datastax, or
other other posts in this mailing list.

Thank you Aaron for the clarification.
May be this could be a feature that Cassandra team should consider
implementing. Instead of two network round trips the logic could be
consolidated on the server side if read before range delete is unavoidable.

Hello,
We have a 6-node ring running 0.8.6 on RHEL 6.1. The first node also runs

SSTables were running. We are using 8GB Java heap on host with 96GB
I've filed https://issues.apache.org/jira/browse/CASSANDRA-3957 as a
bug. Any further light you can shed here would be useful. (Is row
cache enabled? Is JNA installed?)

Read the server log and look for GCInspector output.
