Thanks
once I am using cli script, it is able to connect to the local server
and see all keyspaces etc. Do I still need to load schemas when using
the same local server ?

Are there any limits (implied or otherwise) on how many columns there can be

My understanding has always been that there is no limit on how many columns you
can have in a single row
but i've just read Arin's, WTF is a super column post again and i got the
impression he was

Hi,
version: cassandra 0.6.5
I am trying to bootstrap a new node from an existing seed node.
The new node seems to be stuck with the bootstrapping message, and did not
show any activity.
Only after i checked the logs of the seed node, i realise there has been an
error:

it looks to me like you are describing compaction causes a lot of

things you can do about the extra i/o:
- increase memtable sizes (if you haven't done this yet you should,
by 10x or so)
- reduce compaction priority (see
Ah thanks Jonathan, this is yet again a great explanation to get me started.
Will do some digging. Thanks allot!

Guys,
I was testing ColumnFamilyOutputFormat and found that only columns from the
last Reduce
invocation get stored when
mapreduce.output.columnfamilyoutputformat.batch.threshold has
the default value. Setting it to 1 changes the behavior, and all data is stored
then. Is it the

You can't build Cassandra against trunk thrift, the API has changed.
Stick to the one shipped w/ Cassandra and you will be fine.

Well, 7.0beta1 rejects those patches. Is there a specific revision I can try

They are not copying Cassandra with that, as it was in development for
some time before Cassandra was released (possibly even before
Cassandra development started). The BigTable-esque aspects, if they
are 'copied' from anywhere, are copied from BigTable, just as they are
in Cassandra. The
And having said all that: Azure Table storage model doesn't look like
Cassandra. There is a schema, there are partition keys. It more
resembles something like VoltDB than the map of maps (of maps) of

Thanks Jonathan. I added an extra directory big enough and at least the
bootstrap worked.
However, it brings me to questions that i cant seem to find an answer to.
In my case, i had a 2 node cluster to start with, replication factor of 2,
basically all data residing on both machines. Both nodes
