Joseph Witt commented on NIFI-1035:
-----------------------------------
alan - sounds like you found it via code which is good. You can verify this
for certain by doing 'lsof -p <pid>' and seeing how many of the file handles
are associated with the schema reading (likely will be quite obvious).
Thanks

> AbstractKiteProcessor.getSchema leaks file handles
> --------------------------------------------------
>
> Key: NIFI-1035
> URL: https://issues.apache.org/jira/browse/NIFI-1035
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 0.3.0
> Reporter: Alan Jackoway
>
> We had NiFi nodes crash today with the dreaded too many open files error
> (similar to what I saw in NIFI-888).
> This time, the file handles were all connections to Datanodes in the
> CLOSE_WAIT status.
> The most recent thing I added to our pipeline were ConvertAvroSchema and
> ConvertJSONToAvro processors. I started looking there for a leak and I
> believe I found it in AbstractKiteProcessor.getSchema.
> Pull Request coming shortly.
