> This bug is very similar to HIVE-9436, in that a TTransportException wrapped in a MetaException will not be retried. RetryingMetaStoreClient has a block of code above the MetaException handler that retries thrift exceptions, but this doesn't work when the exception is wrapped.
> {code}
>         if ((e.getCause() instanceof TApplicationException) ||
>             (e.getCause() instanceof TProtocolException) ||
>             (e.getCause() instanceof TTransportException)) {
>           caughtException = (TException) e.getCause();
>         } else if ((e.getCause() instanceof MetaException) &&
>             e.getCause().getMessage().matches("(?s).*JDO[a-zA-Z]*Exception.*")) {
>           caughtException = (MetaException) e.getCause();
> {code}
