  • SHDP namespace | Hadoop Beans configuration order

    In what order are the various Hadoop beans configured?

    While using SHDP namespace, is there is a way to ensure for example that the "hdp:script" is executed before "hdp:cache"? Is there anything similar to the "pre-action" in "hdp:job-runner" for other beans?

    They just respect the Spring container lifecycle, meaning the singletons are initialized first, in their declaring order. hdp:script and hdp:cache are singletons so as long as hdp:cache is declared first (and is picked up first accordingly, before hdp:script) it should be evaluated first.
