    [ https://issues.apache.org/jira/browse/HIVE-23769?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17151406#comment-17151406 ] 

Arman Yazdani commented on HIVE-23769:
--------------------------------------

We are using HDP 3.1 of hive. it seems the JsonSerDe class in HDP converts 1 to false because of this line of code: [https://github.com/hortonworks/hive-release/blob/HDP-3.1.4.53-1-tag/serde/src/java/org/apache/hadoop/hive/serde2/JsonSerDe.java#L284]

> The hive kafka-handler casts all integer values to false for {{JsonSerDe}} if field type is boolean.
> for example if the value in kafka topic be "0" or "1", for both of them the select value of hive kafka-handler external table is false.
