<parse>
  @type csv

</parse>

With this configuration:

2013/02/28 12:00:00,192.168.0.1,111,-

This incoming event is parsed as:

time:
1362020400 (2013/02/28/ 12:00:00)
​
record:
{
  "host"   : "192.168.0.1",
  "req_id" : "111",
  "user"   : "-"
}

If you set null_value_pattern '-' in the configuration, user field becomes nil instead of "-".
