Description:
I have a 2 node cluster with DiskBased tables.
We made a sucsesfull backup with : start backup.
We stopped all ndbd en mysql processes
removed the datafiles as suggested by Jonathan's Blog
When we start the restore we get the following error:
Backup version in files: ndb-6.3.11 ndb version: mysql-5.1.30 ndb-6.3.20
Failed to connect to ndb!!
Failed to initialize consumers
NDBT_ProgramExit: 1 - Failed

How to repeat:
started ndbd --initial
root 19203 1 0 11:12 ? 00:00:00 ndbd --initial
root 19204 19203 0 11:12 ? 00:00:02 ndbd --initial
start the restore:
ndb_restore -b2 -c 172.19.4.39:1186 -n 3 --backup_path=/data/mysql/BACKUP/BACKUP-2 -r
output:
Backup Id = 2
Nodeid = 3
backup path = /data/mysql/BACKUP/BACKUP-2
