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)

  • 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 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.

  • 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)
