Seeing as there aren't even 100 SSTables in L2, LCS should be gradually
trying to compact L3 with L2. You could search the logs for "Adding
high-level (L3)" to check if this is happening.

Depends on if there was a lot of inconsistent data to repair in the first
place. Also full repairs or incremental?
Repairs are complicated and tricky to get working efficiently. If you're

We have a cluster that we are moving to two entire new datacenters to

/usr/local/bin/python is your own source install of python. Using the
system python with cqlsh should "just work" on Jessie with `apt-get
install python'

Thanks Jeff for your reply, yes i agree with what you said but the problem

@Jeff, why does compaction clear them and why does Cassandra keep a handle to
them? Shouldn't they be ignored entirely? Is there an error log I can enable to
detect them?
@kurt, there are no such logs for any of these tables. We have a custom log in
our build of Cassandra that does shows that co

I wouldn't expect compaction to touch them if they're invalid. The handle

Hi, I'm trying to configure Cassandra as a cluster with two nodes. When
trying to simple start the first node just changing this parameters:
listen_address: 10.29.30.2
seed_provider: 10.29.30.2
rpc_address: 10.29.30.2
auto_bootstrap: false
I'm getting this message and then cassandra stop loading:
10.29.30.2 does not appear to be the IP of the node, if you got "Node
/10.29.32.141 state jump to NORMAL" as the first logged state change
from StorageService. Usually this first entry is the node's local IP
address. Later in the log, you'll see OutboundTcpConnection handshakes
and state change fro
If it is blank, you can use bootstrap: true.
What is num_tokens and initial token values?

Please help me understand data migration path from 2.2.3 to 3.7.
1. Tried to take snapshot and load the snapshot using sstableloader; but
it is throwing Streaming Exception.
Please advise.

If you upgrade in place:
Stop each node one at a time
Swap binaries
Start each node
Run upgradesstables when all nodes are bounced
If you want to take data from 2.2 and put it into a 3.x cluster, you'll need to
run upgradesstables on it offline somehow (like clone that 2.2 cluster/schema

You should be able to create it yourself prior to enabling auth without
issues. alternatively you could just add an extra node with auth on, or
switch one node to have auth on then change th RF.
There aren't any ERROR logs for failure to load these files and they do get
compacted away. I'll try to plug some DEBUG logs in a custom Cassandra
version.On Tuesday, August 1, 2017, 12:13:09 PM PDT, Jeff Jirsa

Jeff, Thanks for initial pointer. I want to add some more information to it.
This is to migrate from one cluster (2.2 version) to 3.7 . The client who is in
2.2 cluster they don’t need down time.
So How the data is migrated to new cluster without down time with different
versions?
Thanks,

You can't stream across versions, so you either need to use the native protocol
(do writes with the normal INSERT operations) or you have to get to the right
sstable version
That means one of the three of these:
- export to CSV (copy to/copy from, or Brian Hess' Cassandra-loader on github)
- e
Jeff, I tried the below steps for just 3 rows of data, It looks to be working.
But Confirm me this is right approach.
1. Taking snapshot (using nodetool snapshot) in the existing cluster (2.2
cluster)
2. Bring the snapshot to new cluster and copy in keyspce/table (2.2->3.7)
3.
try with bootstrap true in that case. Start the seed node first. I think it
should work.

Hi Guys,
Sincerely I can't believe the poor log description cassandra has. I'm
really annoyed of it. I'll be very grateful if someone can tell me what
I'm doing wrong.These are the system.log

- Gossiping my schema version
Just curious, why go to 3.7? 3.11 has hundreds of bug fixes that 3.7 doesn’t
and will continue to receive fixes.

Roughly that approach should work, modulo copying data in/out to the right
paths, and making sure you dont overwrite any sstables with the same name.
(You dont need to refresh after the upgradesstables unless you've got 2 3.7
clusters, and you may need to refresh before the upgradesstables if the
28 matches
