Maxim Gekk 3121b411f7 [SPARK-23846][SQL] The samplingRatio option for CSV datasource ... ## What changes were proposed in this pull request? I propose to support the `samplingRatio` option for schema inferring of CSV datasource similar to the same option of JSON datasource: b14993e1fc/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/json/JSONOptions.scala (L49-L50) ## How was this patch tested? Added 2 tests for json and 2 tests for csv datasources. The tests checks that only subset of input dataset is used for schema inferring.
