[https://github.com/apache/hive/blob/550d1e1196b7c801c572092db974a459aac6c249/standalone-metastore/src/main/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java#L345-L351]
{code:java}
private static int nextSerialNum = 0;
private static ThreadLocal<Integer> threadLocalId = new ThreadLocal<Integer>() {
  @Override
  protected Integer initialValue() {
    return nextSerialNum++;
  }
};{code}
 

{{nextSerialNum}} needs to be an atomic value.
