Henning Kropp updated PIG-3554:
-------------------------------
Attachment: TestJobConf.java
A simple UDF to reproduce the Problem. It's a monitored UDF and when executed
on the back-end it prints a out the following log message:
{code}
2013-10-30 19:24:09,516 ERROR TestJobConf:
java.util.concurrent.ExecutionException: java.lang.NullPointerException
2013-10-30 19:24:10,388 ERROR TestJobConf:
java.util.concurrent.ExecutionException: java.lang.NullPointerException
2013-10-30 19:24:10,880 ERROR TestJobConf:
java.util.concurrent.ExecutionException: java.lang.NullPointerException
{code}
Comment out the MonitoredUDF Annotation and you'll this messages:
{code}
Configuration: core-default.xml, core-site.xml, mapred-default.xml,
mapred-site.xml, hdfs-default.xml, hdfs-site.xml, .....
{code}
It should be possible to execute the attached UDF in the following manner:
{code}
A = LOAD 'data' USING PigStorage();
B = FOREACH A GENERATE TestJobConf(*);
DUMP B;
{code}
> JobConf in UDFContext NULL when with @MonitoredUDF
