Object

org.apache.spark.sql.hive.DeserializerLock

public class DeserializerLock
extends Object

Object to synchronize on when calling org.apache.hadoop.hive.serde2.Deserializer#initialize.

[SPARK-17398] org.apache.hive.hcatalog.data.JsonSerDe#initialize calls the non-thread-safe HCatRecordObjectInspectorFactory.getHCatRecordObjectInspector, the results of which are returned by JsonSerDe#getObjectInspector. To protect against this bug in Hive (HIVE-15773/HIVE-21752), we synchronize on this object when calling initialize on Deserializer instances that could be JsonSerDe instances.
