Re: Problems with adding datacenter and schema version disagreement

Hi Olek, Could you solve the problem. Because we are experiencing exactly same issue. We have 4 nodes and all of them are in different schema. Our cassandra version is 2.0.6. Umut On Fri, Mar 21, 2014 at 12:26 AM, Robert Coli wrote: > On Thu, Mar 20, 2014 at 2:23 PM, olek.stas...@gmail.com <

Re: Unable to complete request: one or more nodes were unavailable.

hmm.. I get a similar output as yours yesterday when trying to truncate a table in a 3 nodes cluster where one of the node went offline. but the alternative that I have is that, instead of truncate, i just drop the table and recreate it. using cassandra version 2.0.6 by the way. On Wed, Apr 1

It is not common, but I know of multiple organizations running with RF=5, in at least one DC, for HA reasons. -Tupshin On Apr 15, 2014 2:36 PM, "Robert Coli" wrote: > On Tue, Apr 15, 2014 at 6:14 AM, Ken Hancock wrote: > >> Keep in mind if you lose the wrong two, you can't satisfy quorum. In a

Re: OPSCENTER has table row maintenence?

Thanks Jack I will check it out. The capability I mentioned makes it more productfull to work with Cassandra for minor changes to data so the user does not need to write SQL. -Tony On Tuesday, April 15, 2014 10:21 AM, Jack Krupansky wrote: DevCenter makes it easy to query and display data

Re: OPSCENTER has table row maintenence?

DevCenter makes it easy to query and display data and execute commands against Cassandra, but it doesn’t have a spreadsheet-like tool for hand editing columns. That sounds like a great suggestion to make. See: http://www.datastax.com/what-we-offer/products-services/devcenter -- Jack Krupansky

OPSCENTER has table row maintenence?

Hi All, I asked this over a year ago and it seemed as if OPSCENTER did not have the capability to maintain data like SQL Server Enterprise tool did. I need a visual tool that displays rows and allows me to hand edit column info. Does this tool now do that? Before it was to create schemas and ma

Re: Replication Factor question

Keep in mind if you lose the wrong two, you can't satisfy quorum. In a 5-node cluster with RF=3, it would be impossible to lose 2 nodes without affecting quorum for at least some of your data. In a 6 node cluster, once you've lost one node, if you were to lose another, you only have a 1-in-5 chanc

Re: Replication Factor question

Hi all, thanks for your answers. Very helpful. We plan to use enough nodes so that the failure of 1 or 2 machines is no problem. E.g. for a workload to can be handled by 3 nodes all the time, we would use at least 5, better 6 nodes to survive the failure of at least 2 nodes, even when the 2 nod
