Hi, It looks like you are hitting: https://issues.apache.org/jira/browse/FLUME-1389
The error should be below but I don't see it and this configuration works for me. Are you sure this is the exact configuration which is being used? > agent1.sources.tail.interceptors = hostint > agent1.sources.tail.interceptors.hostint.type = > org.apache.flume.interceptor.HostInterceptor$Builder > agent1.sources.tail.interceptors.hostint.preserveExisting = true > agent1.sources.tail.interceptors.hostint.useIP = false Brock
