Subject Nodetool repair with Load times 5
Date Tue, 18 Aug 2015 07:59:59 GMT
Hi,

I have a phenomena I cannot explain, and I would like to understand.

I’m running Cassandra 2.1.8 on a cluster of 5 nodes.
I’m using replication factor 3, with most default settings.

Last week I done a nodetool status which gave me on each node a load of about 200 GB.
Since then there was no deletes no inserts.

This weekend I did a nodetool -h 192.168.2.100 repair -pr -par -inc

And now when I make a nodetool status I see completely a new picture!!

nodetool -h zennode0 status
Datacenter: datacenter1
=======================
Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
--  Address        Load       Tokens  Owns    Host ID                               Rack
UN  192.168.2.104  940.73 GB  256     ?       c13e0858-091c-47c4-8773-6d6262723435  rack1

UN  192.168.2.101  189.03 GB  256     ?       9af90dea-90b3-4a8a-b88a-0aeabe3cea79  rack1
UN  192.168.2.102  951.28 GB  256     ?       8eb7a5bb-6903-4ae1-a372-5436d0cc170c  rack1
UN  192.168.2.103  196.54 GB  256     ?       9efc6f13-2b02-4400-8cde-ae831feb86e9  rack1

The nodes 192.168.2.101 and 103 are about what they were last week, but now the three other
nodes have a load which is about 5 times bigger!

1) Is this normal?
2) What is the meaning of the column Load?
3) Is there anything to fix? Can I leave it like that?

Strange I’m asking to fix after I did a *repair*.

Thanks a lot for your help.

Kind regards

Jean
