the number of virtual nodes.

because in the typical range query you need to set start and end
token. But in the virtual nodes I realized that tokens are not continuous.

Hi Alicia ,
Cassandra input format creates mappers as many as vnodes. It is a known
issue. You need to lower the number of vnodes :(
I have a simple solution for that and ready to write a patch. Should I
create a ticket about that? I don't know the procedure about that.

records after a
down node comes back. So I assumed that transferring expired records will
not cause any problem.
Do you have any idea? Thank you!

Thank you for the swift response.

Since all hosts are seem to be down, Hector will not do retry. There should
be at least one node up in a cluster. Make sure that you have a proper
connection from your webapps to your cluster.

because we don't want to resurrect deleted columns. Say, sstable A has

You need to change the gc_grace time of the column family. It defaults to

Between 500GB - 1TB is recommended.
But it depends also your hardware, traffic characteristics and
