Multiple MySQL catalogs on EMR/PrestoDB -


i'm able create catalog called mysql on emr using presto-connector-mysql configuration options on emr.

however, i'd connect multiple mysql datasources. adding 2nd datasource /etc/presto/conf/catalog , doing restart presto-server isn't quite right, because while can query mysql datasource correctly , 2nd catalog shows up, querying table there gives:

query 20170407_040307_00008_qjgse failed: no nodes available run query

is there way reset whole cluster? need install new catalog on nodes?

you need install new catalog in /etc/presto/conf/catalog on of nodes, , restart presto. should work fine you.
