Hi,
We recently upgraded from version 1.1 to 1.2
It all went well, including setting up vnodes, but shuffle fails.
We have 2 nodes, hosted on Amazon AWS
The steps we took (on each of our nodes) are pretty straight forward:
1. upgrade binaries
2. adjust cassandra.yaml (keep token)
3. nodetool
I suddenly started to encounter this weird issue after writing some data to
Cassandra. Didn't know exactly what was written before this or due to which
this started happening.

Why are you running such an insanely old version of Cassandra in dev?

Is it how many blocked ever since the server was online? Can somebody explain

Yes, though perhaps more accurate would be that it is often an effect of
performance problems. In general Cassandra flushes memtables because it
believes it needs to. If

I don't think this is strictly true? There's also the periodic flush

There was an interesting thread a while back:
Hi all,
We're using a Cassandra table to store search results in a
table/column family that that look like this:
++-+-+-+
|| 0 | 1 | 2 | ...
++-+-+-+
| row_id | text... | text... | text... | ...
Hi!
I've been wondering... is there anyone in the cassandra-user audience who
has used shuffle feature successfully on a non-toy-or-testing cluster? If
so, could you describe the experience you had and any problems you
encountered?
Thanks!

An alternative to cssh is fabric. It's very flexible in that you can
automate almost any repetitive task that you'd send to machines in a
cluster, and it's written in python, meaning if you're in AWS you can mix
it with boto to automate pretty much anything you want.
