fail to load config of CSV format intput

[WuBingzheng]

I want to use telegraf (version Telegraf 1.8.0~rc1 (git: HEAD 0984fc0d)) to read csv file, but it fails to load config:

[[inputs.tail]]
  files = ["/path/test.csv"]
  data_format = "csv"
  csv_header_row_count = 1

it gives the error:

E! Error parsing telegraf.conf, there must be a header if `csv_data_columns` is not specified

If I use csv_data_columns, it fails too:

[[inputs.tail]]
  files = ["/path/test.csv"]
  data_format = "csv"
  csv_column_names = ["x","y"]

error:

E! Error parsing telegraf.conf, line 4241: field corresponding to `csv_column_names' is not defined in `*tail.Tail'

I am new to telegraf, so I do not know if I config wrong, or is it a bug?

Thanks in advance

Thanks for the report, this appears to be a bug. We will fix this for 1.8.0-rc2.
