> {{*RetryingHMSHandler*}} will retry the failed operations if the exception is caused by {{*JDOException*}} or {{{}*NucleusException*{}}}, the logic is in [RetryingHMSHandler.java#L185:|https://github.com/apache/hive/blob/723d52270488b8dbc108db1a9925d1c569415039/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/RetryingHMSHandler.java#L185]
> {code:java}
>  } else if (e.getCause() instanceof MetaException && e.getCause().getCause() != null) {
>           if (e.getCause().getCause() instanceof javax.jdo.JDOException ||
>               e.getCause().getCause() instanceof NucleusException) {
>             // The JDOException or the Nucleus Exception may be wrapped further in a MetaException
>             caughtException = e.getCause().getCause();
> {code}
> But in {{{}*ObjectStore.java*{}}}, we found some exceptions thrown as {{{}*MetaException*{}}} are not wrapped by the causes, which cause some operations failed by {{JDOException}} can not do retry.
