Hi Daniel,
In my experience when a node shows DN and then comes back up by itself that
sounds some sort of gc pause (especially if nodtool status when run from
the "DN" node itself shows it is up-- assuming there isn't a spotty network
issue). Perhaps I missed this info due to length of thread but
Arindam,
What can you share regarding the source from which you are importing data?
Is it a separate cassandra cluster? If so, how many nodes and datacenters?
What is RF (replication factor) of source cluster? How certain are you that
the rows indeed exist in the set of sstables which you are load
Along the lines of what Ben and Bryan suggested, what are you using to
verify ports are open? If you do something like:
node1$ nc -zv node2 9042
node2$ nc -zv node1 9042
does it succeed from both nodes?
Does the first node 'know' that it is a seed? i.e. do you have first node
listed in its own se
I have a 12 node cluster in prod using vnodes and C* version 2.18. I have
never used rebuild, and instead prefer bootstrapping new nodes, even if it
means there is additional shuffling of data and cleanup needed on the
initial nodes in each DC, mostly b/c you can tell when bootstrapping is
finished
To elaborate on what Robert said, I think with most things technology
related, the answer with these sorts of questions (i.e. "ideal settings")
is usually "it depends." Remember that technology is a tool that we use to
accomplish something we want. It's just a mechanism that we as humans use
to exe
Yes, you can examine the actual sstables in your cassandra data dir. That
will tell you what version sstables you have on that node.
You can refer to this link:

I found via google search phrase "sstable versions" to see wh
