Anyone know any good open source database management tool like Opscenter for Apache Cassandra? Opscenter only work for Apache Cassandra version 2.1 below but we are using Apache Cassandra version 3.5 so Opscenter wont work. Thanks Phuong

Does sstabloader work between datastax cassandra and apache cassandra?
I'm trying to copy data from dse 5.0.7 to apache 3.11.1 cassandra version
It shouldn't be an issue to use it to export between Datastax Cassandra and the open source version, if they are the same versions.
Having said that, please note that DSE 5.0.7 uses Apache 3.0.11, as explained in the release notes. This means that you should import the data to a cluster with that version, and once that this is completed, upgrade to 3.11.1.
Disclosure: I'm not a DSE user, I don't have a way to test this.
I've having some issues with my Cassandra cluster and I would like to install OpsCenter Community in order to debug what's going on.
I've found this and this pages talking about the compatibility between DataStax OpsCenter and Cassandra, but this don't list Cassandra 2.2.5 (actually I'm using DataStax Cassandra - dsc 22).
My question is: can I use DataStax OpsCenter (free / community version) within Cassandra 2.2.5? If not, there's an alternative?
No, the docs you cited indicate that OpsCenter doesn't support any cassandra greater than 2.1.x and the next version of opscenter (6.x) will only support Datastax Enterprise. I don't know of another visual front-end to cassandra at this time.
I have been building an application using Apache Cassandra 2.2.0 for sometime now. We plan to start using the DataStax Enterprise 4.8.5 (this is built on Apache Cassandra 2.1.3).
Problem is as this is a downgrade of Cassandra version, 2.2.0 -> 2.1.3, I am not able to read the SSTables created by Cassandra version 2.2.0.
What can I do to have my old data available with DSE 4.8.5?
This is not supported. You should consider contacting Datastax for advice (that's one of the advantages of paying for DSE, you get someone to talk to about topics like this).
You'd almost certainly have to export the data and re-import it (either using sstable2json or COPY TO+COPY FROM to export it to a CSV using CQLSH, or using something like Spark or CQLSSTableWriter to recreate 2.1 sstables.
I'm new to cassandra, can some one provide steps to upgrade from DataStax Enterprise 4.6.1 TO DataStax Enterprise 4.7 with Cassandra 2.1
This should get you where you'd like to go: http://docs.datastax.com/en/upgrade/doc/upgrade/datastax_enterprise/upgradeDSE47.html
Since you're new to Cassandra, I suggest reading the docs over and over - even doing this in a test environment first. While upgrades are fairly straight forward (depending on node count and amount of data), there's no real easy way of reverting from Cassandra 2.1 (DSE 4.7) to Cassandra 2.0 (DSE 4.6). So make sure you have snapshots of sstables from DSE 4.6 before proceeding.
I am working for a small concern and very new to apache cassandra. Studying about cassandra and performing some small analytics like sum function on cassandra DB for creating reports. For the same, Hive and Accunu can be choices.
Datastax Enterprise provides the solution for Apache Cassandra and Hive Integration. Is Datastax Enterprise is the only solution for such integration. Is there any way to resolve the hive and cassandra integration. If so, Can I get the links or documents regarding the same. Is that possible to work the same with the windows platform.
Is any other solution to perform analytics on cassandra DB?
Thanks in advance .
I was trying to download DataStax Enterprise (DSE) for Windows but found there is no such option on their website. I suppose they do not support DSE for Windows.
Apache Cassandra does have builtin Hadoop support. You need to set up a standalone Hadoop cluster colocated with Apache Cassandra nodes and then use ColumnFamilyInputFormat and ColumnFamilyOutputFormat to read/write data from/to your Hadoop cluster.
