----------------------------------
hi [~cos] ...
- replacing {{init-hdfs.sh}} can be done easily, just by using the results of
BIGTOP-952, which is already in bigtop.
- this patch, i was confused about the right way to to integrate groovy, modify
spec files to package it, and so on. now that i understand bigtop better, i
think its really close to being done.
- we delete {{provision.groovy}} but i think thats b/c we are copying it to
{{init-hcfs.groovy}} for consistency
- *yes* not a bad idea to have {{init-hdfs.sh}} wrap {{init-hcfs.groovy}} with
hdfs semantics.
> Combine BIGTOP-1200 and BIGTOP-952 with a few minor shell commands that will
> entirely replace init-hdfs.sh

> Key: BIGTOP-1235
> URL: https://issues.apache.org/jira/browse/BIGTOP-1235
> Project: Bigtop
> Issue Type: Improvement
> Components: general
> Affects Versions: 0.7.0
> Reporter: jay vyas
> Assignee: jay vyas
> Priority: Critical
> Fix For: 0.9.0
>
> Attachments: BIGTOP-1235.first.patch, BIGTOP-1235.patch
>
>
> BIGTOP-1200 provides file schema in JSON format, for any HCFS related tool to
> read.
> BIGTOP-952 meanwhile give us fast provisioning by running in a single JVM
> (without multiple haoop fs -... commands_).
> Thus, when those two are finished, we can replace init-hdfs.sh (with the
> exception of a few extra shell commands in bottom of that script which still
> will need to be called).
> So this JIRA will:
> - create a new init-hcfs.groovy script which calls provision.groovy in
> BIGTOP-952, with init-hcfs.json as input.
> - add in the remaining straggler commands from init-hdfs.sh which dont fit
> into the generic json format as shell commands.
> - delete init-hdfs.sh entirely
> - update puppet scripts to use init-hcfs.groovy, calling them with the "hdfs"
> argument.
