David Jones created PIO-25: ------------------------------ Summary: Don't attempt to start PostgreSQL when it's not being used Key: PIO-25 URL: https://issues.apache.org/jira/browse/PIO-25 Project: PredictionIO Issue Type: Improvement Reporter: David Jones Priority: Trivial
When running: {{pio-start-all}}, even if your {{pio-env.sh}} file is setup to use HBase and not PostgreSQL you'll see "postgresql: unrecognised service": {quote} Starting Elasticsearch... Starting HBase... starting master, logging to /PredictionIO/vendors/hbase-1.2.2/bin/../logs/hbase--master-2898ebbfb9d1.out postgresql: unrecognized service Waiting 10 seconds for HBase to fully initialize... Starting PredictionIO Event Server... {quote} This is because {{pio-start-all}} simply tries to detect if PostgreSQL is running, if it isn't, then it will go ahead and try to start it: https://github.com/apache/incubator-predictionio/blob/develop/bin/pio-start-all#L64 What would be better is if we checked {{PIO_STORAGE_REPOSITORIES_METADATA_SOURCE}}, {{PIO_STORAGE_REPOSITORIES_EVENTDATA_SOURCE}} and {{PIO_STORAGE_REPOSITORIES_MODELDATA_SOURCE}} to see if any of those have been set to {{PGSQL}}. If they have not been set to {{PGSQL}} then we don't need to attempt to start PostgreSQL every time. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
