Greg Phillips created HIVE-11288: ------------------------------------ Summary: Avro SerDe InstanceCache returns incorrect schema Key: HIVE-11288 URL: https://issues.apache.org/jira/browse/HIVE-11288 Project: Hive Issue Type: Bug Reporter: Greg Phillips
To reproduce this error, take two fields in an avro schema document matching the following: "type" : { "type": "array", "items": [ "null", { "type": "map", "values": [ "null", "string" ] } ] } "type" : { "type": "map", "values": [ "null" , { "type": "array", "items": [ "null" , "string"] } ] } After creating two tables in hive with these schemas, the describe statement on each of them will only return the schema for the first one loaded. This is due to a hashCode() collision in the InstanceCache. A patch will be included in this ticket shortly which removes the hashCode call from the InstanceCache's internal HashMap, and instead provides the entire schema object. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
