--------------------------------
Summary: PropertiesFileConfigurationProvider provides poor error
messages for misconfiguration
Key: FLUME-1187
URL: https://issues.apache.org/jira/browse/FLUME-1187
Project: Flume
Issue Type: Bug
Components: Configuration, Technical Debt
Affects Versions: v1.1.0
Reporter: E. Sammer
We need to beef up the proactive configuration sanity checking of PFCP. We have
some blind references that can generate NPEs. One example of this is if a
source doesn't specify the channels property.
