------------------------------------------

             Summary: Field Metadata raises NullPointerException in hashCode method
                 Key: SPARK-24742
                 URL: https://issues.apache.org/jira/browse/SPARK-24742
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.3.1
            Reporter: Kaya Kupferschmidt


The class org.apache.spark.sql.types.Metadata has a method *putNull* for storing null pointers as Metadata. Unfortunately the hashCode method throws a NullPointerException when there are null values in a Metadata object, rendering the *puNull* method useless.

h2. How to Reproduce
The following code will raise a NullPointerException
{code}
new MetadataBuilder().putNull("key").build().hashCode
{code}
