Hi,
When we connect to Opscenter using an account, we do not see any disconnect
button to connect under another account.
Thanks

Hi,
Our Hadoop jobs will only do READs and we want to restrict reads in this

What can we do to achieve this goal ?

have different dynamic_snitch_badness_threshold values on
Hi,
What's the procedure to remove authentification ?
I have set authenticator to org.apache.cassandra.auth.AllowAllAuthenticator in

right ! authorizer was still set. I didn't know there was 2 different classes
for handling logging and access.

The issue came from a different configuration (cassandra-env.sh) of the chosen
node. It was not using the CMS garbage.

I tried to use your quick workaround but the task is lasting really longer than
before even if it uses 2 mappers in //. The fact is that there are 1000 tasks.
Are you using vnodes ? I didn't try to disable them.

Unfortunately I've just tried with a new cluster with RandomPartitioner and it

Hi,
I'm using Pig to calculate the sum of a columns from a columnfamily (scan of
all rows) and I've read that input data locality is supported at
http://wiki.apache.org/cassandra/HadoopSupport
However when I execute my Pig script Hadoop assigns only one mapper to the task
and not one mapper on

We're also waiting for this bugfix :(

So, you're saying that deleted rows can come back even if the node is always up

Hi Cyril,

Hi,
I know that deleted rows can reappear if node repair is not run on every node
before gc_grace_seconds seconds. However do we really need to obey this rule if
we run node repair on node that are down for more than max_hint_window_in_ms

No one else concerned by the fact that we must define the column families the

Is there a way to have the column family defined the new way in a DC and the
old way (WITH COMPACT STORAGE) in another DC ?

Hi,
I'm testing Pig (0.11) with Cassandra (1.2.2). I've noticed that when the
column family is created without WITH COMPACT STORAGE clause, Pig can't find it
:(
After searching in the code, I've found that the issue comes from the function
recv_describe_keyspace. This function returns a KsDef
It succeeds but returns nothing as my columnfamily has only data for columns
appearing in the CREATE TABLE order. It you want to keep it you should provide
the CREATE order with sample data

I'm trying to execute your sample pig script and I don't understand where the
alias columns comes from :
grunt rows = LOAD 'cassandra://MyKeyspace/MyColumnFamily' USING
CassandraStorage();
grunt cols = FOREACH rows GENERATE flatten(columns);
I suppose it's defined by the call to getSchema
Finally I've found the answer in CassandraStorage.java !
columns is not an alias but a bag that you fill with columns (name+value) that
don't have metadata.
That's why your sample doesn't return anything in my test as I've only filled
existing columns (found in the CQL CREATE command)

what do you mean ? it's not needed by Pig or Hive to access Cassandra data.

Hi,
I know that DataStax Enterprise package provide Brisk, but is there a community
version ? Is it easy to interface Hadoop with Cassandra as the storage or do we
absolutely have to use Brisk for that ?
I know CassandraFS is natively available in cassandra 1.2, the version I use,
so is there
I don't want to write to Cassandra as it replicates data from another
datacenter, but I just want to use Hadoop Jobs (Pig and Hive) to read data from
it. I would like to use the same configuration as

I want to know
Here is the point. You're right this github repository has not been updated for
a year and a half. I thought brisk was just a bundle of some technologies and
that it was possible to install the same components and make them work together
without using this bundle :(

Hi,
FYI, I've added the devel version to the cassandra formula of the homebrew
package installer, and updated the release version to 1.1.8.
You can now use brew install cassandra to install version 1.1.8 and brew
install --devel cassandra to install version 1.2.0-rc2
enjoy !

Nice job Aaron,
AFAIU now you set the gc_before to the current time for secondary indexes. And
as it was set to Integer.MAX_VALUE before your patch, removeDeletedStandard
function was testing if (column.getLocalDeletiontime() MAX_VALUE) which is
always true and so was removing all rows from
32 matches
