Claus Ibsen commented on CAMEL-6867:
------------------------------------
Yeah good point of using the uuid generator from Camel.
And yeah fell free to change that prefix or make it configurable etc, as you
think its the best.
> camel-hdfs - HdfsProducer filename collisions when Producer instance recreated
> ------------------------------------------------------------------------------
>
> Key: CAMEL-6867
> URL: https://issues.apache.org/jira/browse/CAMEL-6867
> Project: Camel
> Issue Type: Bug
> Components: camel-hdfs
> Reporter: Ben O'Day
> Assignee: Ben O'Day
> Fix For: Future
>
>
> The HdfsProducer uses an instance variable (long splitNum) that is
> incremented to create unique output filenames in a given directory (seg0,
> seg1, etc).
> If the Producer instance is recreated (producer cache limit exceeded, server
> restart, etc), the splitNum variable is reset to 0. This results in files
> being overwritten when using overwrite=true mode or throwing "The file
> already exists" errors when using overwrite=false mode.
> We should switch to using a timestamp or some other unique generator to
> prevent filename collisions regardless of the Producer instance lifecycle for
> the same hdfs directory URL...
