> schemaInference option not to convert strings with leading zeros to int/long
> -----------------------------------------------------------------------------
>
> Key: SPARK-21978
> URL: https://issues.apache.org/jira/browse/SPARK-21978
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.1.0, 2.1.1, 2.2.0, 2.3.0
> Reporter: Ruslan Dautkhanov
> Labels: csv, csvparser, easy-fix, inference, ramp-up, schema
>
> It would be great to have an option in Spark's schema inference to *not* to
> convert to int/long datatype a column that has leading zeros. Think zip
> codes, for example.
> {code}
> df = (sqlc.read.format('csv')
> .option('inferSchema', True)
> .option('header', True)
> .option('delimiter', '|')
> .option('leadingZeros', 'KEEP') # this is the new
> proposed option
> .option('mode', 'FAILFAST')
> .load('csvfile_withzipcodes_to_ingest.csv')
> )
> {code}
