Node failure during the dropping of a table could lead to the node hanging when attempting to restart.
When this happened, the
NDBinternal 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
NDBinternal operation timed out. To aid in debugging such occurrences, a new dump code,
DUMP DictDumpLockQueue), which dumps the contents of the
DICTlock queue, has been added in the ndb_mgm client. (Bug #14787522)
