Out of interest, are you using the hbase formatter?
{quote}
No, I just use the default formatter with indent and max length changed. Only new code is
formatted, old code is "format" manually to keep the patch clean...
I will try the hbase formatter later. I found it when looking for test-patch.sh, thanks.

You going to try hbase-it?
{quote}
Yes I have run it with 'mvn verify' under hbase-it. There are some fails and errors, I need
to see the source code to identify the reason.

Thanks.

> Currently the flush decision is made using the aggregate size of all column families.
When large and small column families co-exist, this causes many small flushes of the smaller
CF. We need to make per-CF flush decisions.
