I filed a JIRA https://issues.apache.org/jira/browse/CASSANDRA-11741 to track

You can use SparkShell to access Cassandra via the Spark Cassandra
connector. The getting started article on our support page will probably
give you a good steer to get started even if you’re not using Instaclustr:

bq. Can you use HiveContext for Cassandra data?
Most likely the above cannot be done.

Hi,
Has anyone tried accessing Cassandra data using SparkShell? How do you do
it? Can you use HiveContext for Cassandra data? I'm using community version
of Cassandra-3.0
Thanks,

Thanks very much.
I understand that the data needs to be read from the DB to get the next
‘PagingState’.
But is it possible not to return those data to the client side, just returning
the ‘PagingState’?
I.e. the data is read on the server side, but not return to client side, this
can save some
It really depends how close you want to stay to the most current versions of
open source community products.
Cloudera has tended to build more products that requires their distribution to
not be as current with open source product versions.

Hi guys
We are thinking of using one the 3 big data platforms i.e hortonworks , mapr or
cloudera . Will use hadoop ,hive , zookeeper, and spark in these platforms.
Which platform would be better suited for cassandra ?

Hi,
What’s the 3.0.6 release date? Seems like the code has been frozen for a few
days now. I ask because I want to install Cassandra on Ubuntu 16.04 and
CASSANDRA-10853 is blocking it.
Best,
Drew
Note that incremental repair strategies (2.1+) run anti-compaction against
sstables in the range being repaired, so this will prevent overstreaming
based on the ranges in the repair session.

Yup, with repair and particularly bootstrap is there is a decent amount of
"over streaming" of data due to the fact it's just sending an sstable.

Update: It was actually the driver update (from 2.1.9 to 3.0.1) that solved
the issue. I reverted by C* Server back to 2.2 and my test is still ok.

In a truly consistent world (should I say "snapshot isolation" world
instead), re-reading the same page should yield the same results no matter
how many new inserts have occurred since the last page read.
Caching previous page at app level can be a solution but not viable if the
amount of data is
Hi Doan,
What does it have to do being eventual consistency? Lets assume a scenario
with complete consistency and we are at page X, and at the same time some
inserts/updates happened at page X-2 and we jumped to that.
User will see inconsistent page in that case as well, right? Also in such
cases
I just retried with Cassandra 3.0.5 and it performs much better. Not a
single of these illegal results.
I guess my recommendation for anyone using CAS is: Upgrade to >= 3.x :-)

Don't be fooled, despite saying tcp6 and :::*, it still listens on IPv4. As
far as I'm aware this happens on all 2.1 Cassandra nodes, and may just be
an oddity of netstat. It would be unrelated to your connection timeout
issues, that's most likely related to firewall/network issues.

"Is it possible to just return PagingState object without returning data?"
--> No
Simply because before reading the actual data for each page of N rows, you
cannot know at which token value a page of data starts...
And it is worst than that, with paging you don't have any isolation. Let's

dHi, All,
We are considering to use DataStax java driver in our codes. One important
feature provided by the driver we want to use is 'paging'.
But according to the
https://datastax.github.io/java-driver/3.0.0/manual/paging/, it seems that we
can't jump between pages.
Is it possible to just re
It doesn't work ,still using ipv6 [image: 内嵌图片 1]
And I already set [image: 内嵌图片 2]
Now I'm using 4.1.1 using 9160 port instead of 5.x.x。
Hopefully this could be resolved, Thanks!

Hi Jack,
sorry to keep you busy :-)
There definitely is a column named "value" in the table. And most of the
time this codepath works fine, even when my CAS update fails. But in very
rare cases I get a ResultSet that contains applied=false but does not
contain any value column.
