Background
Exasol nodes are assigned ids, by default continuously allocated starting from 11. e.g. a 4 node system will have nodes with node ids 11, 12, 13 and 14.
In some specialized scenarios it can be useful to explicitly assign node id to hosts.
New Feature
It is now possible to assign node ids to hosts during installation by setting CCC_HOST_NODE_IDS, e.g.:
CCC_HOST_NODE_IDS='11 12 13 20 21 22'
Requirements:
- Node ids must be >= 11
- Node ids must not contain duplicates
- Number of node ids must match number of hosts in CCC_HOST_ADDRS
The node ids are assigned to the hosts in CCC_HOST_ADDRS in order.
