MySQL Cluster 7.2 Release Notes  /  Changes in MySQL Cluster NDB 7.2  /  Changes in MySQL Cluster NDB 7.2.7 (5.5.25a-ndb-7.2.7) (2012-07-17)

Changes in MySQL Cluster NDB 7.2.7 (5.5.25a-ndb-7.2.7) (2012-07-17)

MySQL Cluster NDB 7.2.7 is a new release of MySQL Cluster, incorporating new features in the NDB storage engine, and fixing recently discovered bugs in previous MySQL Cluster NDB 7.2 releases.

Obtaining MySQL Cluster NDB 7.2. MySQL Cluster NDB 7.2 source code and binaries can be obtained from

This release also incorporates all bugfixes and changes made in previous MySQL Cluster releases, as well as all bugfixes and feature changes which were added in mainline MySQL 5.5 through MySQL 5.5.25a (see Changes in MySQL 5.5.25a (2012-07-05)).

Bugs Fixed

  • Important Change: When FILE was used for the value of the LogDestination parameter without also specifying the filename, the log file name defaulted to logger.log. Now in such cases, the name defaults to ndb_nodeid_cluster.log. (Bug #11764570, Bug #57417)

  • Packaging: Some builds on Solaris 64-bit failed because the packages exceeded the 2GB limit for the SVR4 installation layout. Now such packages are built without the embedded versions of mysqltest and mysql-client_test to save space. (Bug #14058643)

  • If the Transaction Coordinator aborted a transaction in the prepared state, this could cause a resource leak. (Bug #14208924)

  • When attempting to connect using a socket with a timeout, it was possible (if the timeout was exceeded) for the socket not to be set back to blocking. (Bug #14107173)

  • An error handling routine in the local query handler used the wrong code path, which could corrupt the transaction ID hash, causing the data node process to fail. This could in some cases possibly lead to failures of other data nodes in the same node group when the failed node attempted to restart. (Bug #14083116)

  • A shortage of scan fragment records in DBTC resulted in a leak of concurrent scan table records and key operation records. (Bug #13966723)

  • Attempting to add both a column and an index on that column in the same online ALTER TABLE statement caused mysqld to fail. Although this issue affected only the mysqld shipped with MySQL Cluster, the table named in the ALTER TABLE could use any storage engine for which online operations are supported. (Bug #12755722)

  • Packaging; Cluster API: The file META-INF/services/org.apache.openjpa.lib.conf.ProductDerivation was missing from the clusterjpa JAR file. This could cause setting openjpa.BrokerFactory to ndb to be rejected. (Bug #14192154)

    References: See also Bug #52106.

  • Cluster API: libndbclient did not include the NdbScanFilter class. (Bug #14010507)

  • Cluster API: When an NDB API application called NdbScanOperation::nextResult() again after the previous call had returned end-of-file (return code 1), a transaction object was leaked. Now when this happens, NDB returns error code 4210 (Ndb sent more info than length specified); previouslyu in such cases, -1 was returned. In addition, the extra transaction object associated with the scan is freed, by returning it to the transaction coordinator's idle list. (Bug #11748194)
