Accessing a table having a
BLOBcolumn but no primary key following a restart of the SQL node failed with Error 1 (Unknown error code). (Bug #13563280)
At the beginning of a local checkpoint, each data node marks its local tables with a “to be checkpointed” flag. A failure of the master node during this process could cause either the LCP to hang, or one or more data nodes to be forcibly shut down. (Bug #13436481)
A node failure while a
ANALYZE TABLEstatement was executing resulted in a hung connection (and the user was not informed of any error that would cause this to happen). (Bug #13416603)

Cluster Replication: Under certain circumstances, the
Rowscount in the output of
SHOW TABLE STATUSfor a replicated slave
NDBtable could be misreported as many times larger than the result of
SELECT COUNT(*)on the same table. (Bug #13440282)
