Remove unused and obsolete function
The Node.str function is very old and is not useful since the nodeobjects have much more fields today. This patch removes it, and ifneeded a full node display can be done via ‘show’.
Add node memory field to Node objects
This patch adds a new n_mem field to the node objects, and implementsread/save/show support for it. The field is not currently used (exceptin the node list) but will be used for checking data consistency andinstance up/down status.
Pass actual types to node/instance constructors
This patch changes the parameters passed to the node and instanceconstructors from generic Strings (which are then parsed via “read”) tothe actual used types, by converting them earlier in Cluster.loadData.
Some small changes in preparation for hscan
This patch does some small changes: - fixes a comment - export more node functions (unneeded now, but hscan will use them) - fixes Makefile rule for building the programs
Add a separate type for the [(Int, String)] list
This is added for better readability, since this is very often used indeclarations.
Handle correctly offline nodes in cluster scoring
This patch changes two things with regard to offline nodes: - first, it only calculates the various coefficients across online nodes - second, it adds a new score denoting the percentage of instances...
Show offline nodes in the node status list
This patch adds a new ‘-’ flag for the node status which denotes offlinenodes.
Restrict move list based on offline node status
This patch changes the Cluster.checkInstanceMove function to restrictthe target move list based on which nodes are online.
Add command line support for offlining nodes
This patch modifies hbal (only, hn1 not yet) for setting nodes offline.
Add a new 'offline' Node attribute
This patch adds a new node attribute - offline - which will serve toskip nodes from the target candidate list.
