Description:
According to https://dev.mysql.com/doc/refman/5.7/en/mysql-cluster-ndbd-definition.html#ndbparam-ndbd-s... setting StartPartitionedTimeout = 0 will make a starting data node wait indefinitely to avoid a partitioned restart. However, in practice 0 means no wait.
How to repeat:
1. Configure a cluster with two data nodes and NoOfReplicas = 2 with StartPartitionedTimeout = 0
2. Stop all data nodes
3. Start one of the data nodes
From the cluster log:

...
So it waits for 30 seconds to avoid a partial start, but then immediately starts a partitioned start.
Suggested fix:
Change so 0 means indefinite according to the documentation.
