Re: onPropertyModified doesn't seem to work

[Mark Payne]

Sivaprasanna,

What package is your processor class in? By default, the logging for the
org.apache.nifi.processors package is set to WARN. I am wondering if you are
simply not seeing the logging because of your logback configuration. I would 
recommend
you instead add a breakpoint and attach to your running nifi instance.

Thanks

onPropertyModified doesn't seem to work

[Sivaprasanna]

Hi everyone,

I'm facing problem getting onPropertyModified() working. Just to test it
and troubleshoot further, I created a custom processor, the usual
MyProcessor sample processor. I then added the following:

@Override
public void onPropertyModified(PropertyDescriptor descriptor, final
String oldValue, final String newValue) {
LOG.info("Property modified for processor " + this.getIdentifier());
super.onPropertyModified(descriptor, oldValue, newValue);
}

And modified onTrigger to generate a string and write it as an output
flowfile. The processor seems to work. However, when I modify the value for
the property and restart it, I expect the above log statement to be
generated, but it is not. Any help is appreciated. Thanks.

Re: Not able to add "Max Rows Per Flow File" property in SelectHiveQL

[Sivaprasanna]

Max Rows Per Flow File is a property that was introduced fairly recently. I
think it was after NiFi 1.4.0/1.5.0. Since yours is NiFi 1.3, the framework
doesn’t know/understand it. You can try downloading and using NiFi 1.5.0
version of Hive bundle.
