Apache Spark commented on SPARK-21954: -------------------------------------- User 'viirya' has created a pull request for this issue: https://github.com/apache/spark/pull/19167 > JacksonUtils should verify MapType's value type instead of key type > ------------------------------------------------------------------- > > Key: SPARK-21954 > URL: https://issues.apache.org/jira/browse/SPARK-21954 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 2.2.0 > Reporter: Liang-Chi Hsieh > > {{JacksonUtils.verifySchema}} verifies if a data type can be converted to > JSON. For {{MapType}}, it now verifies the key type. However, in > {{JacksonGenerator}}, when converting a map to JSON, we only care about its > values and create a writer for the values. The keys in a map are treated as > strings by calling {{toString}} on the keys. > Thus, we should change {{JacksonUtils.verifySchema}} to verify the value type > of {{MapType}}. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
