> It seems, metastore operations are slow in this cluster and hence concurrent
> writes/DDL operations are failing to lock the row for update.
> Currently, the sleep interval between retries is specified via the config
> *hive.notification.sequence.lock.retry.sleep.interval*. The default value is
> 500 ms which seems to be too small. Can we set higher values for sleep
> interval and retries count,
> *hive.notification.sequence.lock.retry.sleep.interval=10s*
> *hive.notification.sequence.lock.max.retries=10*
