Bugs Fixed
Accessing a table having a BLOB
column but no primary key following a restart of the SQL node
failed with Error 1 (Unknown error code).
(Bug #13563280)
A node failure while a ANALYZE
TABLE statement was executing resulted in a hung
connection (and the user was not informed of any error that
would cause this to happen).
(Bug #13416603)
References: See also Bug #13407848.
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)
Cluster Replication:
Under certain circumstances, the Rows count
in the output of SHOW TABLE
STATUS for a replicated slave
NDB table could be misreported as
many times larger than the result of
SELECT
COUNT(*) on the same table.
(Bug #13440282)
