Re: [RELEASE] Apache Cassandra 2.1.0

2014-09-17 Thread abhinav chowdary 
it depends on how you installed it, package vs tar ball etc , Datastax has
good documentation i suggest reading it
http://www.datastax.com/documentation/upgrade/doc/upgrade/cassandra/upgradeCassandraDetails.html

in either case at a high level

Step 1: Stop node
Step 2: Backup your config files
Step 3: will be to replace new binaries
Step 4: will be to run nodetool upgradesstables

Again there are some gotchas so i recommend reading above documentation
thoroughly before proceeding

 Well, how to upgrade from 2.0.x to 2.1? Just replace cassandra bin files?

 One question. Where can users get a java Datastax driver to support this

Re: cassandra + spark / pyspark

2014-09-11 Thread abhinav chowdary 
Adding to conversation...

there are 3 great open source options available

1. Calliope http://tuplejump.github.io/calliope/
This is the first library that was out some time late last year (as i
can recall) and I have been using this for a while, mostly very stable,
uses Hadoop i/o in Cassandra (note that it doesn't require hadoop)

2. Datastax spark cassandra connector
https://github.com/datastax/spark-cassandra-connector: Main difference is
this uses cql3, again a great library but has few issues, also is very
actively developed by far and still uses thrift for minor stuff but all
heavy lifting in cql3

3. Startio Deep https://github.com/Stratio/stratio-deep: Has lot more to
offer if you use all startio stack, Deep is for Spark, Statio Streaming is
built on top of spark streaming, Stratio meta is something similar to
sharkor sparksql and finally stratio Cassandra which is a fork of Cassandra
with advanced Lucene based indexing

Read Entire row from cassandra

2014-04-17 Thread abhinav chowdary 
We have one use case where we need to pull the entire wide row from
Cassandra (using 2.0, DSE4.0 ). Is there a preferred way to do this? ,
currently we are using prepared statement with java driver..
