Hi All -
I am trying to bootstrap a replacement node in a cluster, but it consistently
fails to bootstrap because of OOM exceptions. For almost a week I've been going
through cycles of bootstrapping, finding errors, then restarting / resuming
bootstrap, and I am struggling to move forward. Some
Just curious, has anybody created a debian package for this?
Thanks, Jesse

Hi,
I am using spark 1.6. I wrote a custom receiver to read from WebSocket. But
when I start my spark job, it connects to the WebSocket but doesn't get
any message. Same code, if I write as separate scala class, it works and
prints messages from WebSocket. Is anything missing in my Spark Code? Th
You can build one on your own very easily. Just check out the desired git
repo and do this:

Hi,
probably you can try to start new node with auto_bootstrap: false and then
repair keypaces or even tables one by one with nodetool repair

Hello,
I am trying to rebuild a new Data Center with 50 Nodes, and expect 1 TB / node.
Nodes are backed by SSDs, and the rebuild is happening from another DC in same
physical region. This is with 2.1.13.
I am doing this with stream_throughput=200 MB, concurrent_compactors=256,

We are not publishing the build artefacts for our LTS at the moment as we
don't test them on the different distros (debian/ubuntu, centos etc). If
anyone wishes to do so feel free to create a PR and submit them!

Hi,
I am by no means an expert on Cassandra, nor on
DateTieredCompactionStrategy. However, looking in "Query 2.xlsx" I see a
lot of
Partition index with 0 entries found for sstable 186
To me, that looks like Cassandra is looking at a lot of sstables and
realize too late that they don't conta
Hi,
Let's say I am periodically making snapshots of a table, say "users", for
backup purposes. Let's say a developer makes a mistake and corrupts the
table. Is there an easy way for me to restore a replica, say
"users_20161102", of the original table for the developer to looks at the
old copy?

You would have to build some logic on top of what’s natively supported.
Here is an option:

Hi Jens,
When you refer to restoring a snapshot for a developer to look at, do you
mean restoring the cluster to that state, or just exposing that state for
reference while keeping the (corrupt) current state in the live cluster?
You may find these useful:

Thanks Anubhav,
Looks like a Java project without any documentation whatsoever ;) How do I
use the tool? What does it do?
Cheers,

Based on most of what I've said previously pretty much most ways of
avoiding your ordering issue of the leap second is going to be a "hack" and
there will be some amount of hope involved.

Hi,
I have following problem with Jython UDF.
1) I'm using Cassandra 3.9 deb packages and Ubuntu 14.04. I'm running

2) I added jython jar to /usr/share/cassandra/lib. (jython version 2.7.0)
This makes creating python function possible
