Write Inconsistency to update a row
I have two Cassandra 2.0.5 servers running with some datas inserted, where
each row have one empty column. When the client send a lot of update
commands to fill this column in each row, some lines update their content,
but some lines remain with the empty column.
Using one server, this never happens!
Any suggestions?
Tks.

Make sure you've got ntpd running, otherwise this will be an ongoing nightmare.

Are you sure all the nodes are working at that time?
Yes. They are working.
I would suggest increasing the replication factor (for example 3) and use CL=ALL or QUORUM to find out what is going wrong.
I did! I still have the same problem.

This seems like a hinted handoff issue but since you use CL = ONE it should happen.
Are you sure all the nodes are working at that time? You could use nodetool status to check that.

I’m assuming you don’t have any errors (timeouts etc) on the write site

Did you make sure all the nodes are on the same time? If they're not,
you'll get some weird results.

Yes. They are working.

I did! I still have the same problem.

This seems like a hinted handoff issue but since you use CL = ONE it should
happen.
Are you sure all the nodes are working at that time? You could use nodetool
status to check that.
I would suggest increasing the replication factor (for example 3) and use
CL=ALL or QUORUM to find out what is going wrong.

replication_factor=1
CL=ONE
Does the data show up eventually?
Yes.
Can be the clocks?

What is your keyspace replication_factor?
What consistency level are you reading/writing with?
Does the data show up eventually?
I’m assuming you don’t have any errors (timeouts etc) on the write site
