> HIVE-16886 introduced a retry logic; which has a configurable retry interval. unfortunately
{{HiveConf}} has some public fields which at first glance seems to be usefull to pass as arguments
to other methods - but in this case the default value is not even loaded into the field read
by the code.. and because of that the innocent client code [here|https://github.com/apache/hive/blob/a974a9e6c4659f511e0b5edb97ce340a023a2e26/metastore/src/java/org/apache/hadoop/hive/metastore/ObjectStore.java#L8554]
 have used a {{-1}} value incorrectly which eventually caused an exception [here|https://github.com/apache/hive/blob/a974a9e6c4659f511e0b5edb97ce340a023a2e26/metastore/src/java/org/apache/hadoop/hive/metastore/ObjectStore.java#L8581]:
