Description

When a user have multiple options like path, paTH, and PATH for the same key path, option/options is non-deterministic because extraOptions is HashMap. This issue aims to use CaseInsensitiveMap instead of HashMap to fix this bug fundamentally.

spark.readStream
  .option("paTh", "1")
  .option("PATH", "2")
  .option("Path", "3")
  .option("patH", "4")
  .option("path", "5")
  .load()
...
org.apache.spark.sql.AnalysisException:
Path does not exist: file:/.../1;
