Nathan Howell created SPARK-19641: ------------------------------------- Summary: JSON schema inference in DROPMALFORMED mode produces incorrect schema Key: SPARK-19641 URL: https://issues.apache.org/jira/browse/SPARK-19641 Project: Spark Issue Type: Bug Components: SQL Affects Versions: 2.1.0 Reporter: Nathan Howell
In {{DROPMALFORMED}} mode the inferred schema may incorrectly contain no columns. This occurs when one document contains a valid JSON value (such as a string or number) and the other documents contain objects or arrays. When the default case in {{JsonInferSchema.compatibleRootType}} is reached when merging a {{StringType}} and a {{StructType}} the resulting type will be a {{StringType}}, which is then discarded because a {{StructType}} is expected. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
