Hi Mikhail,

Let me check what does this value to see if I can find a relation on not
starting jmx4 service.
Thanks,

Nothing needs to happen for the writetime() to be valid. It's basically the
underlying timestamp so it's part of the insert itself.
Now, you don't give a whole lot of detail so it's hard to guess what could
be the problem. But since you mention that you get 0, not null, I'd suggest
to double
Mikhail,
tested it setting it to default value 360 and it stopped crashing!
That's awesome! I love this mailing list ;-)
Thanks a lot,

Hi all,
We made a decision to use compact storage for a couple of very large

Hi,
We have a Cassandra cluster of 28 nodes. Each one is an EC2 m1.xLarge based
on datastax AMI with 4 storage in raid0 mode.
Here is the ticket we opened with amazon support :
This raid is created using the datastax public AMI : ami-b2212dc6. Sources

hi all;
What is the best way to integrate cassandra pig-extension with oozie?
can be configure oozie to use pig-cassandra instead of pig?
Some ideas that I thinking are:
Launching a Shell jobthat runs ./pig-cassandra script.pig
or changing environment variables vakues
or the original
If I remember correctly when I configured pig, cassandra, and oozie to work
together, I just used vanilla pig but gave it the jars it needed.
What is the problem you’re experiencing that you are unable to do this?

hi Jeremy,
I do not try test it still, I only test examples pig from oozie project
without cassadra.
* pig-cassandra* sets the cassandra pig libraries .jar in the the
PIG_CLASSPATH env var. and after call the original shell script *pig* from
PIG_HOME/bin/pig and , up to now, I launch pig
I believe what I did was when I set up Oozie with the setup script where you
specify the version of Hadoop and such, I also added additional jars like the
Cassandra jars and some of its dependencies there and the cassandra.yaml,
cassandra-env.sh and potentially the topology properties file.
What happens when you don't start the JMX service? That field has a default
in both cassandra.yaml and in Config.java:

This may be a bug that could be fixed with simply adding a null check
I can reproduce this with the mx4j lib loaded by setting to max hint window
to 'empty':
max_hint_window_in_ms:
I guess you could call this a bug, but given that it has 2 defaults, you
have to explicitly set this to empty in the configuration to cause any
exceptions.

Hi Sylvain,
That is correct - we currently have only primary-key columns, and wish to add a
single non-primary key column. Based on the data stored in the table, it is
highly unlikely we will need to add more columns in the future, but we can
always migrate the data then if we need to.
We
Thanks Rob. Let me add one thing in case someone else finds this thread -
Restarting the nodes did not in and of itself get the schema disagreement
resolved. We had to run the ALTER TABLE command individually on each of the
disagreeing nodes once they came back up.

This article[1] cites gains in read performance can be achieved when
compression is enabled. The more I thought about it, even after reading the
DataStax docs about reads[2], I realized I do not understand how
compression improves read performance. Can someone provide some details on
this?

I hope I get this right :)
Thanks for contributing :)
a repair will trigger a mayor compaction on your node which will take up a
lot of CPU and IO performance. It needs to do this to build up the data
structure that is used for the repair. After the compaction this is streamed

I¹m trying to estimate our disk space requirements and I¹m wondering about
disk space required for compaction.
My application mostly inserts new data and performs updates to existing data
very infrequently, so there will be very few bytes removed by compaction. It
seems that if a major compaction
