Hi
I have a single node Cassandra running datastax distribution. I reinstall
Cassandra and updated cassandra.yaml data_file_directories.
But now I run nodetool cfstats I got SSTable count: 0
This is the output of nodetool cfstats
Keyspace: kairosdbRead Count: 0Read Latency: NaN ms.

Hi,
I'm trying to import CSV data using the COPY ... FROM command. After
importing 10% of my 2.5 GB csv file the operation aborts with the message:
Request did not complete within rpc_timeout.
Aborting import at record #504631 (line 504632). Previously-inserted values
still present.
There are
I have done with bulk loader with key_validation_class=LexicalUUIDType for
new row with the help of this [code][1] but i have changed my
**key_validation_class=AsciiType** in order to make **string as row keys**
create column family Users1
with key_validation_class=AsciiType
If not getting any exception.
Reason for Request did not complete within rpc_timeout. = socket time

As per http://www.datastax.com/docs/1.1/references/cql/COPY( COPY from CSV
section)
COPY FROM is intended for importing small datasets (a few million rows or
less) into Cassandra. For

**string as row keys**
why not key_validation_class=UTF8Type ?

I am not able to get your meaning for *string as row keys ? *

Row key values will be of type key_validation_class only

Here i mean that key_validation_class=AsciiType or
key_validation_class=UTF8Type
but I am unable to create an sstable for this column family
create column family Users1
with key_validation_class=UTF8Type
and comparator=AsciiType
AND column_metadata = [

Hi,
thanks for you reply. My CSV contained roughly 5 million rows. It aborted
after half a million row. It seems to me that some throttling mechanism is
missing in the implementation of the COPY command?
I'll try the other way of getting data in.

Hi,
I was playing around with cassandra off-heap options. I configured 3 GB
off-heap for my row cache and 2 GB Heap space for cassandra. After
running a bunch of load tests against it I saw the cache warm up. Doing
a jmap histogram I noticed a lot of offHeapkey objects. At that point my
row
I found the issue below concerning inactive client connections (see Cassandra

are using Cassandra 1.2.4 and the Cassandra JDBC driver as client. Is this
still an existing issue?

While you normally would not allow access to a MySQL server, it is done in
many instances like shared hosting.
Also mysql does support a max fail connection attempts feature that will
blacklist an IP for a time.
