## Expected Behavior Lookup tables should be updated. ## Current Behavior …In the log file I get messages like this: 2018-04-21T16:20:31.544-04:00 ERROR [LookupDataAdapter] Couldn't refresh data adapter <lladdr-lookup/5aa40ca39d992d72500b1b83/@7e3d1a53> java.lang.NullPointerException: null Also when I create a lookup table or insert rows in an existing CSV file, the lookup doesn't work. ## Possible Solution Is it related to my version of Java? I'm just using the current latest version of Java, 1.8.0_162. Is Graylog not compatible with this version of Java? ## Context ## Your Environment * Graylog Version: 2.4.3 * Elasticsearch Version: 5.5.3 * MongoDB Version: 3.2.19 * Operating System: Ubuntu server 16.04 * Browser version: Chrome 64.0.3282.186

## Expected Behavior It should be great if we can have multi value with CSV d…ata adapter in Lookup Table. I have a lot of use cases where i have to create multiple lookup tables with the same CSV file but different infos retrieved; Discussion with @joschi in the Graylog forum (https://community.graylog.org/t/some-questions-about-lookup-tables/2655): > Do you have an example use case for this? > Yes, i have to populate some logs with values from our LDAP. So i have a script which generate me a CSV file with all my users and all the fields that are important to us. So for one user, i will lookup at his UID and get values for knowing if it’s a staff member, a researcher, a student. In the same CSV i also have the value for this user of the department, the course, … So today, i have 3 CSV data adapters (and more to come) with the same CSV file :frowning: if we can just have multi-value it will be great !! ## Current Behavior Not possible ## Your Environment * Graylog Version: 2.3
