Hi,
I’m getting repeated NullPointerException reported for an ExtractText processor
(processing the resultant splits from a ListenSyslog) thus:
datanode2-cm1.mis-cds.local:9092ExtractText[id=4372efbf-efcf-3065-acd4-b8fdb91d64fb]
ExtractText[id=4372efbf-efcf-3065-acd4-b8fdb91d64fb] failed to process due to
java.lang.NullPointerException; rolling back session:
java.lang.NullPointerException
The same error appears for each node in my cluster too so not specific to one
node.
I have enabled additional logging for ExtractText processor (I think) by adding
<logger name="org.apache.nifi.processors.standard.ExtractText" level=“DEBUG"
additivity="false">
<appender-ref ref="USER_FILE"/>
</logger>
To each logback.xml on each node, but this doesn’t give any more details as to
why the NPE.
Flowflies are getting through the processor but concerned about the errors as
clearly something isn’t correct so suggestions welcome.
Thanks
Conrad
