Bruno Freudensprung updated UIMA-2143:
--------------------------------------
Description:
If you have this remote Vinci cas processor (configured to continue in case of
error) in a CPE (that has 4 processing pipelines):
{{<casProcessors casPoolSize="5" processingUnitThreadCount="4">
<casProcessor deployment="remote" name="Analytics2">
<descriptor>
<include href="Default_Analytics2.xml"/>
</descriptor>
<deploymentParameters>
<parameter name="vnsHost" type="string" value="localhost"/>
<parameter name="vnsPort" type="string" value="9000"/>
<parameter name="service-access" type="string"
value="exclusive"/>
</deploymentParameters>
<errorHandling>
<errorRateThreshold action="continue" value="3/1000"/>
<maxConsecutiveRestarts action="continue" value="5"
waitTimeBetweenRetries="30000"/>
<timeout max="2700000" default="-1"/>
</errorHandling>
<checkpoint batch="1" time="1000ms"/>
</casProcessor>}}
When the corresponding Vinci service is restarted during the CPE execution, the
CPE cannot correctly reconnect the 4 pipelines to the 4 instances of the Vinci
service. This happens only in a multiple processing units environment.
This is due to the fact that, in case of error, the failed CasProcessors are
put in a list of failed processors and that processors are never removed from
this list. The consequence is the CPE always try to fix the first processor.
The problem seems to be located in:
uimaj-cpe/src/main/java/org/apache/uima/collection/impl/cpm/container/deployer/vinci/VinciCasProcessorDeployer.java
Patch proposal attached.
