Node failure during the dropping of a table could lead to the node hanging when attempting to restart.
When this happened, the
internal dictionary (
DBDICT) lock taken by
the drop table operation was held indefinitely, and the logical
global schema lock taken by the SQL the drop table operation
from which the drop operation originated was held until the
NDB internal operation timed out. To aid in
debugging such occurrences, a new dump code,
which dumps the contents of the
queue, has been added in the ndb_mgm client.
