MemSQL Partition has no master instance

Running queries on a MemSQL tables returns the following error.

Error Code: 1777. Partition db_name:0 has no master instance.

I understand MemSQL Enterprise avoids this error from coming in the first place; however, I tried dropping the table, truncating data, and restarting the cluster several times, yet I still get the same error. Any ideas how to fix this error?

Does "SHOW LEAVES" show all leaf nodes as online? In redundancy 1 you need all leaves online to run queries. Run REMOVE LEAF if you want to permanently remove an offline leaf from the cluster.
