Oleg,
The system keyspace is not replicated it is local to the node. You should
check your logs to see if there are Timeouts from streaming hints, i
believe the default value to stream hints it 10 seconds. When i ran into
this problem i truncated hints to clear out the space and then ran a repair

Per driftx in #cassandra, this is probably *not* 6297 because only a single
flush is involved. If you haven't, I would consider filing a Cassandra
Increasing the phi value to 12 can be a partial workaround. It's certainly
not a fix, but it does partially alleviate the issue. Otherwise hang in
there until 1.2.12. Aaron is probably right that this is aggravated on
under powered nodes, but larger nodes can still see these symptoms.

Oh ! Thanks.
Is there any workaround to avoid the problem while waiting for update ?

OpsCenter only has limited CQL support. In the latest versions you should
be able to see tables created with CQL but you aren't able to modify them
or browse the data. For those type of operations we recommend DevCenter -

Sure:
package com.footnote.tools.cassandra;

public class Test

well, I download a copy from http://cassandra.apache.org/download/ and

Hi,
You said : Adjusted cassandra.yaml as above except that for seeds put both

If you put the new node into the seeds list, your node will not bootstrap.
This could explain why you see only the half of your data.
Can you check in system.log ?
By the way, you can retry without
Hi,
We are facing problem while upgrading Cassandra which is available in the DSE

Below is the error log we are getting while starting Cassandra.

OpsCenter will still report metrics for CQL tables, it just doesn't allow
creating/modifying/browsing them. DevCenter does not include any sort of
metrics.

Can we also see traffic getting generated on our cluster on that table
using DevCenter? Just like we used to see traffic getting generated on the
tables created via CLI interface on the OpsCenter? like read request, write
requests, total compactions etc etc

Hi,
We are testing the process of adding a node to a cluster using a simple
procedure, and seeing data loss.

Here is what we did:

You can't just drop in Apache Cassandra over DSE since it adds custom
replication strategies like this one.

Looks like the read timeouts were a result of a bug that will be fixed in
2.0.3.
I found this question on the Datastax Java Driver mailing list:

which led me to:

I just experimented the same thing on our 28 m1.xlarge C*1.2.11 cluster.
phi_convict_threshold is default : 8. I will try increasing it to 12 as 12
seems to be the good value :)
That's still weird to see all nodes marked down at once. I never
experimented this before using vnodes...
