Hi Shalab,
Are you using anything in your WHERE clause of the query?
If not, you are doing a full scan of your data. In iteration 8 it will scan 1
500 000 entries, and the default time out value is pretty low.
If you do select count(*) from traffic_by_day where segment_id = 1 and day = 1
it
000
files. (can be found in /etc/init.d/cassandra, FD_LIMIT).
However, with the 2.0.x I had to raise it to 1 000 000 because 100 000 was too
low.
Kind regards,
Pieter Callewaert

I know the ppl of datastax are now investigating this, but no fix yet...

Thanks, it works perfectly with ALTER TABLE. Stupid I didn't thought of this.
Maybe I overlooked, but maybe this should be added in the docs. Really a great
feature!

Hi Brian,
Which version of cassandra are you using? And are you using the BOF to write to
Cassandra?
Kind regards,

We also have 4-disk nodes, and we use the following layout:
2 x OS + Commit in RAID 1
2 x Data disk in RAID 0
This gives us the advantage we never have to reinstall the node when a drive
crashes.

Does this have to do something with the new directory structure from 1.1 ? Or
are the parameters changed from the function?

if this is a bug or a breaking change ?

Had the same problem this morning, seems related to the leap second bug.
Rebooting the nodes fixed it for me, but there seems to be a fix also without

Hi,
In 1.1 the commitlog files are pre-allocated with files of 128MB.
(https://issues.apache.org/jira/browse/CASSANDRA-3411) This should however not
exceed your commitlog size in Cassandra.yaml.
commitlog_total_space_in_mb: 4096

You may want to upgrade all your nodes to 1.1.
The streaming process connect to every living nodes of the cluster (you can
explicitely diable some nodes), so all nodes need to speak 1.1.
