SHARD_RESERVED_PRIOR_INIT_PLACEMENT_CWOBJ4806=CWOBJ4806I: Shard {0} has been reserved on container {1} prior to initial placement. Shard will be placed onto this container when initial placement occurs.
Explanation
A shard was reserved on the container, but initial placement has not occurred. Initial placement can be gated by several factors. The number of started containers remaining less than the numInitialContainers configured is the most common.
User response
If numInitialContainers is configured, start enough containers to trigger placement. See the Deployment topology configuration section in the information center for more information on numInitialContainers and deployment policies.
