Athena - remove quotes and skip the first line in a GZIP compressed CSV file

0

Hi,

I've tried to run the following DDL statement in Athena:

querying GZIP compressed CSV files

For some reason, it won't remove the first line, neither the quotes character (") from the output.

I've found a relevant thread on AWS forums where other people that ran into this issue as well: https://forums.aws.amazon.com/thread.jspa?messageID=755357&threadID=244207&tstart=0

Would love to hear your thoughts about this.

DDL Statement:

Neither skip.header.line.count nor quoteChar are supported in Athena at this time.

In particular, quoteChar is not valid for the LazySimpleSerde (ROW FORMAT DELIMITED). It is a property of OpenCSVSerde, which is not supported in Athena yet.
