I'm also facing problems regarding corrupt sstables and also couldn't run
sstablescrub successfully.
I restarted my nodes with disk failure policy "best_effort", then I run the
"nodetool scrub "
Once done I removed the corrupt tables manually and started repair

Sorry for the late reply, I ran the nodetool resetlocalschema on all nodes but
in the end it just removed all the schemas and crashed the applications.
I need to reset and try again. I’ll try get you the gc stats today ☺

We have 2 clusters running DSE. On one of the clusters we recently added
additional nodes to a datacenter.
On the cluster where we added nodes, we are getting authentication issues
from client. We are also unable to "list users" on system_auth keyspace.
It's getting stuck.

Is it safe to make schema changes ( e.g. create keyspace and tables ) on
multiple separate nodes of a cluster while they are out of communication
with other nodes in the cluster? For example create on node A while node B
is down, create on node B while A is down, then bring both up together.

Hi Stephen,
If you manage to create tables on each node while node A and B are separated,
you’ll get into troubles when they will reconnect again. I had the case
previously and Cassandra complained that tables with same names but different
ids were present in the keyspace. I don’t know if there

What version of Cassandra are you running? It sounds like the disk failure
policy is incorrectly being applied to scrub, which kind of defeats the
purpose of it. I'd recommend opening a ticket (
https://issues.apache.org/jira/browse/CASSANDRA) with the information you
posted here.

Hi Jacques-Henri
You are right - serious trouble. I managed some more testing and it does
not repair or share any data. In the logs I see lots of:
WARN [MessagingService-Incoming-/10.50.16.214] 2015-10-02 16:52:36,810
IncomingTcpConnection.java:100 - UnknownColumnFamilyException reading from
soc
Why don’t you simply let the node join the cluster? It will pull new tables and
the data automatically.

We have a 12node Cassandra cluster running on 1.2.12. Each node is using 1.1TB
out of 2TB. Each node has a min+max heap of 24Gb and the physical server has
48Gb. Our nodes do not restart during the week, only on the weekend, and we're
observing that the off heap memory that is consumed ramps

Yep, fixed in 2.1.10.

When I run the query "SELECT image FROM roll WHERE roll = :roll“ against this
table
CREATE TABLE roll (
roll INT,
image BIGINT,
data VARCHAR static,
mid VARCHAR,
imp_st VARCHAR,
PRIMARY KEY ((roll), image)
) WITH gc_grace_seconds = 3456000 AND compaction = { 'class' :
'LeveledCompactionStrategy'
Ah. My bad for not checking the jira first.
Thanks!

You could use a two key space method. At startup, wait some time for the
node to join the cluster.
the first time the app starts, you can be in one of three states:
The happiest state is that you succeed in joining a cluster. in this case
you will get replicated the cluster's keyspace and can s
