Subject CAS pge-configuration - stage file on batch stub without shared filesystem
Date Mon, 05 Oct 2015 16:28:10 GMT


I would like to implement the following scenario (all components are
virtually separated host, implemented as a linked docker containers


1.       [PUSHPULL] - The push pull component download files to the staging

2.       [CRAWLER] - The crawler component extracts metadata and triggers
filemgr ingestion

3.       [FILEMGR] - Filemgr ingest metadata in solr and archives the
ingested file

4.       [CRAWLER] - Sends a ProductType-Ingest event to WMGR

5.       [WMGR] - Receives the event that trigger a data processing
workflow: the ingested file should be processed and a new data product
should be generated and ingested

6.       [RMGR] - Handles the request to schedule the processing task and
dispatches it to the batch stub

7.       [BATCHSTUB] - a configured batch stub performs the processing task
over the ingested file and produces the new data product


I already implemented 1,2,3,4,5,6 but  I'm stuck with a problem:


How can I instruct the batchstub to query the filemgr, initiate a data
transfer to stage the source data product in a directory on the batch stub
host, perform the processing and then stage back the new product? I would
like to not rely on a shared filesystem.


Any help would be really appreciated.


Best regards

Andrea Fonti
