In a project Severalnines is engaged in, we are developing a realtime application based on Cluster/J. To start with, I must say cluster/j is fantastic and so far I am very happy with it and beaten our expectations big time. It is quite new however and we stumbled on a couple of issues, but those were fixed very fast by the Cluster/J developers. The bugs we encountered were:
1. Download the cmon binary package to a monitoring host Currently there are binaries available for Linux 64-bit and 32-bit (statically linked) and works for MySQL Cluster 7.0.9 and later 7.0.x versions and also 7.1.x.
In this case the monitoring host will be on 'ndb05' (IP address 10.0.1.5) - see 9. [Read more...]
connection handling - cmon will now retry connects forever. cmon will also recover and automatically reconnect to cluster after a cluster failure or if the connection to the mysql server crashes where cmon logs information. This means you will have to terminate the cmon using e.g 'killall cmon' or /etc/init.d/cmon stop
disk data - cmon now gathers information about the amount of table space used and this is presented in the web interface
init.d scripts - fixed bugs in creating the init.d scripts during make install-extra
fixed compiler warnings - now 0 compiler warnings on Linux systems
mysql_statistics table - now explicitly using engine=myisam
