Github user pasalkarsachin1 commented on the issue:
https://github.com/apache/storm/pull/1942
> The current FileReader implementation is expected to have constructor
with a specific signature, which cannot be enforced at compile time. IMO, this
should also be fixed along with this patch by introducing some init method in
the FileReader interface.`
I am thinking to work on this after this patch we can have init() api which
verifies things before it proceeds.
> It enforces implementation to be Serializable, which HDFS classes (fields
in FileReader implementations) are not. That seems why HdfsSpout instantiates
FileReader in open method.`
Once we provide init method we are providing user a way to initialize the
non Serializable member.
