Error with Indexes

I added to more nodes to my cluster. I put them in a separate node group and everything ran fine for a week. Then I noticed that the new nodes didn't have much data so I ran the alter table command to redistribute the data. During that, the cluster crashed. I could not restart it and was forced to restore from backup. Now, however, I get this error:

| xxxx | analyze | Error | Got error 4721 'Mysqld: index stats thread not open for requests' from NDB |
| xxxx | analyze | Warning | index stats (RPK) for key vote_id: unexpected error 4721 |
| xxxx | analyze | Warning | index stats (RPK) for key vote_id: unexpected error 4721 |
| xxxx | analyze | status | Operation failed

Everything is working very slowly so I assume that indexes are not being used. I did not import indexes the data restoration, but did run the rebuild command separately. Does anyone have any idea what to do about this problem?
