Alan Jackoway commented on NIFI-1035:
-------------------------------------
FWIW I did look over AbstractHadoopProcessor as well as Get/Put HDFS processors
and didn't see anything that stood out. Given that both times I've had issues
like this the file handles have built up very quickly, I'm guessing we would
have seen it if Get/Put HDFS were the culprits.
> 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.
