> Note: *The patch FLUME - 2207 is required to reproduce the issue.*
> The following code causes the flume agent to crash a stack trace when starting (illegal pattern passed to {{FastDateFormat}}) : 
> {code}
> agent1.sinks.sinkEls.indexNameBuilder.dateFormat = %{format}
> {code}
> In practice, we need a variable to customize the index rotation (daily, weekly, monthly) from a header. (the header is defined in a morphline in our case, configured as an interceptor on the source)
> The problem happens because the {{FastDateFormat}} is instanciated in the method {{configure}}. We could delay its instanciation inside the method {{getIndexName}} without decrease the performance of the agent ({{FastDateFormat}} uses caching extensively). I added a patch to present this implementation.
