> Project: Apache Apex Malhar
> Issue Type: Bug
> Reporter: Priyanka Gugale
> Assignee: Priyanka Gugale
>
> AbstractFileOutputOperator opens the file in append mode when file already
> exists.
> AbstractFileOutputOperator uses hadoop FileSystem to do file operations. But
> some of the implementations of FileSystem like FTPFileSystem, S3FileSystem
> does not support "append" operation.
> To address this we need to either
> 1. Avoid using function calls which has support restrictions.
> 2. Write extensible code so that one can change the logic to avoid certain
> function calls.
