Subject CsvInputFormat - read header line first
Date Wed, 31 Oct 2018 04:50:50 GMT
Hi,

When we are splitting a csv file into multiple parts we are not sure which
part is read first. Is there any way to make sure first part with header is
read first ? I need to read header line first to store column name vs index
and use this index for processing next records.

I could read header line from the file before submitting job to the flink,
but that way we are opening the file 2 times. Is there any better way to do
this? Please suggest.
