Tom White updated WHIRR-266:
----------------------------
Priority: Major (was: Blocker)
Fix Version/s: (was: 0.5.0)
Andrei pointed out that this isn't a blocker for 0.5.0 since not all the
services need to be converted. Since I'm having some problems getting the HBase
service converted (some kind of race with the thrift server) I'm removing this
as a blocker.
> Separate tasks of both install and configuration scripts into more generic
> and detailed functions

> Project: Whirr
> Issue Type: New Feature
> Components: core
> Reporter: Hyunsik Choi
>
> Using whirr, I experimented some problems. Especially, if at least one of the
> steps for installing and configuring a service meets some exception or error,
> whirr cannot construct the running cluster. In another case, some of entire
> clusters do not startup by whirr due to unknown reasons. In both cases, users
> have to recover them manually. It may be really burden for users.
> However, the current implementation does not support any recovery ways. In
> addition, service scripts (install and post-configure) bundles up too many
> tasks. For example, for hadoop service the configuration script mounts
> devices, configures *-site.xml files, and executes the service start script.
> It makes users hard to reuse that scripts.
> Thus, I propose that we separate both scripts (i.e., install and
> post-configure) into more normalized and detailed functions, such as
> *service-clean, service-install, service-configuration, service-start, and
> service-stop*. In addition, they should be executable individually by a user.
> I expect that it will give us many benefits: 1) it makes debugging easier 2)
> when an exception or error occurs during starting a service, a user can
> recover easily the cluster by using appropriate functions.
