This script automatically configures N temporary local clusters on the machine and then
|
|
calls a command while these clusters are running. As soon as the command returns, all
|
|
configured clusters are killed and all generated data is deleted.
|
|
|
|
The purpose of this is to support testing a set of integration tests using multiple clusters
|
|
(i.e. using the Multi-threaded client).
