- Added EL support to "Directory" property of ListHDFS and GetHDFS processors
- Added EL support to "Destination" property for ConsumeJMS and PublishJMS processors
- Added EL support to "MQ ConnectionFactory Implementation", "MQ client library path", "Broker URI" properties for the JMS Connection Factory Provider
- Added EL support to "Database Connection URL", "Database Driver Class Name", "DB Driver jar url", "DB username", and "DB password" properties for the DBCP Connection Pool
- Removed NotificationServiceManagerSpec.groovy, previous PR from Joe Witt covers the needed testing for Variable Registry/Value Lookup at this time
This closes#778.
Current implementation of DBCPConnectionPool was attempting to test if connection could be obtained via dataSource.getConnection().
Such call is naturally a blocking call and the duration of the block is dependent on driver implementation. Some drivers (e.g., Phoenix - https://phoenix.apache.org/installation.html)
attempts numerous retries before failing creating a deadlock when attempt was made to disable DBCPConnectionPool which was still being enabled.
This fix removes the connection test from DBCPConnectionPool.onConfigured() operation returning successfully upon creation of DataSource.
