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.

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.

Please provide your keyspace definition, and the output of "nodetool ring"

It is not common, but I know of multiple organizations running with RF=5,
in at least one DC, for HA reasons.

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.

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.

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

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
