Hi,
Have a question regarding the mirror of git://git.apache.org/cassandra.git
and github.
How are the repositories synchronized? Manually, some kind of automatic job
doing this..

Hi, Everyone:
I'm importing a CSV file into Cassandra, and it always get
error:Request did not complete within rpc_timeout , then I have to
continue my COPY command of cql again. And the CSV file is 2.2 G . It is
taking a long time.
How can I speed up csv file importing ? Is there
Hello,
I saw this earlier yesterday but didn't want to reply because I didn't know
what the cause was.
Basically I using wide rows with cassandra 1.x and was inserting data
constantly. After about 18 hours the JVM would crash with a dump file. For
some reason I removed the compaction throttling
Hi all,
We have the case of a cassandra cluster with nodes version 2.0.10, all in a
single EC2 region. We want to perform a rolling upgrade to version 2.1.2
but the new node has the following exceptions:
java.lang.RuntimeException: Unable to gossip with any seeds

Hello Chao Yan,
CSV data import using Copy command in cassandra is always painful for
large size file (say 1Gig).
CQL tool is not developed for performing such heavy operations instead try
using SSTableLoader to import.

Thank you very much for your advice.
Can you give me more advice for using SSTableLoader to import csv ?
What is the best practice to use SStableLoader importing csv in Cassandra ?

Hi,
I was wondering, how would auto_bootstrap behave in this scenario:
1. I had a cluster with 3 nodes (RF=2)
2. One node died, I deleted it with nodetool removenode (+ force)
3. A new node launched with auto_bootstrap: true
The question is: will the right vnodes go to the new node as if it
was
This is a follow-up to my previous post “Cassandra taking snapshots
automatically?”. I’ve renamed the thread to better describe the new information
I’ve discovered.
I have a four node, RF=3, 2.0.11 cluster that was producing snapshots at a
prodigious rate. I let the cluster sit idle overnight

Yes. Of course, TokenAwarePolicy can wrap any other policy.
2) the TokenAwarePolicy actually is doing the job that
The Apache git repo is the main repo. The github repo is periodically
synched (I believe every few hours).

I'd be really interested to know what sort of performance or load
improvements you see by
doing client side partitioning. Please post back some results if you've
tried that strategy.

I have a cluster on C* 2.1.1 and jdk 1.7_u51. I have a trouble with full gc

the latency of cluster will be increased.

I have two kinds of machine:
16G RAM, with default heap size setting, about 4G.
64G RAM, with default heap size setting, about 8G.
These two kinds of nodes have same number of vnodes, and both of them have
gc issue, although the node of 16G have a higher probability of gc issue.
Thanks,

as per my knowledge if you have externally NOT specified
-Dcassandra.replace_address=old_node_ipaddress then new tokens (randomly)
would get assigned to bootstrapping node instead of tokens of dead node.

I recommend reading through
https://issues.apache.org/jira/browse/CASSANDRA-8150 to get an idea of how
the JVM GC works and what you can do to tune it. Also good is Blake
Eggleston's writeup which can be found here:
