Asynchronous disconnection of mysqld from the cluster caused any subsequent attempt to start an NDB API transaction to fail. If this occurred during a bulk delete operation, the SQL layer called
HA::end_bulk_delete(), whose implementation by
ha_ndbclusterassumed that a transaction had been started, and could fail if this was not the case. This problem is fixed by checking that the transaction pointer used by this method is set before referencing it. (Bug #20116393)
