Chandra,
Try adding the following option, which may give you more info in the log or
console.
-Xcheck:jni
Do you have any custom c++ libraries using JNA interface?You should add
your custom libraries in LD_LIBRARY_PATH
or provide them in -Djava.library.path.

Hi,
I am new to Cassandra Environment, does the order of the ring matter, as
long as the member joins the group?

Hi,
Can you share the GC logs for the systems you are running problems into?

I think you are building from the source, were there any build failures,
before you started the test?
can you rebuild and try again? Please provide the command line you are
using as well?

Sorry, I am not understanding the problem, and I am new to Cassandra, and
want to understand this issue.
Why do we need to use wide row for this situation, why not a simple table
in cassandra?
todolist (user, state) ==> is there any other information in this table
which needs for processing to
Also, may be you need to check the read consistency to local_quorum,
otherwise the servers still try to read the data from all other data
centers.
I can understand the latency, but I cant understand how it would save
money? The amount of data transferred from the AWS server to the client
should
I am just learning, I don't know answer to your question, but What is the
use case for TTL as 1 second?

I am new and trying to learn Cassandra.
Based on my understanding of the problem, almost 2Gb is taken up just for
the compression headers heap.
And 100MB per SSTable, and about 30,000 files gives about 3TB of data?
What is the hardware and memory configuration you are using to provide this
large
Could be your -Xmn800M is too low, that is why it is trying garbage
collecting very frequently.
Do you have any statistics on how much memory it is collecting on every
cycle?

It depends on what JVM you are running.

Rudger,
I am trying this on 2.0.5 to see, but both Scala code and AST code are
going to different tables? Can you give the exact AST code you are trying?

I have a two node cluster. Tried with both 2.0.4 and 2.0.5.
I have tried your code, and exactly after inserting 127 rows, the next

Sylvain,
I am trying ccm to install and it does from source directory, I have tried
2.0.4/3/2/1 and 1.2.15, all of them are reporting the same failure after
127 records inserted.
I am using 1.56.34 and 1.56.38 client both reports the same issue.
Is something wrong with the client or the server,
.
create keyspace test1 with replication = { 'class':'SimpleStrategy',
'replication_factor':1};
CREATE TABLE IF NOT EXISTS wide (
time varchar,
name varchar,
value varchar,
PRIMARY KEY (time,name))
WITH COMPACT STORAGE;
