Hello All,
We are seeing some issue when we add more nodes to the cluster, where new
node bootstrap is not able to stream the entire metadata and fails to
bootstrap. Finally the process dies with OOM (java.lang.OutOfMemoryError:
Java heap space)
But if I remove few nodes from the cluster we don't
d the stream throughput on the existing hosts?

Jeff,
any idea if this is somehow related to :
https://issues.apache.org/jira/browse/CASSANDRA-11840?
does increasing the value of streaming_socket_timeout_in_ms to a higher
value helps?

When enabling Authentication on cassandra, is it required to set the RF
same as the no.of nodes(

Hello,
We have cassandra cluster in 3 regions with version 2.1.13, and all of a
sudden we started seeing lot of hints accumulating on the nodes. We are
pretty sure there is no issue with the network between the regions and all
the nodes are up and running all the time.
Is there any other reason f

Hello,
I am trying to upgrade the cassandra version from the 3.0.8 to 3.0.14. I am
adding a new node with 3.0.14 version to 3.0.8. cluster and I see the
schema disagreement between the nodes and the new node doesn't stream any
data.
I am looking at : https://issues.apache.org/jira/browse/CASSAN

I am trying to evaluate the JMX hints metrics for cassandra(TotalHints).
However, when I am testing the metrics, the total hints accumulated count
shows perfectly fine, but when the hints are replayed and the hints

I am trying to understand pros and cons of tuning(increasing) the bloom

increasing the value.
I am using LeveledCompactionStrategy, so the default bloom_filter_fp_chance

One more better way if you would like to do using cli is

Hello,
I have Cassandra cluster(2.1.16) where the application is using the legacy
thrift schema (Cassandra-cli). I am planning to upgrade the cluster to
3.11.X without changing the schema. but the new 3.x doesn't have
cassandra-cli utilities. is there any alternative to get the cli installed
on 3.
