Bugs Fixed

  • Node failure during the dropping of a table could lead to the node hanging when attempting to restart.

    When this happened, the NDB 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, DUMP 1228 (or DUMP DictDumpLockQueue), which dumps the contents of the DICT lock queue, has been added in the ndb_mgm client. (Bug #14787522)
