Hi, 


I'm trying to submit a streaming job using the -conf option to specify
  
a job configuration file. 


One of the options in my configuration file is stream.addenvironment   
but this option doesn't appear to be getting set; i.e when I run the   
job and use the web interface to look at job.xml this property is   
missing. 


Does anybody have any ideas? 


My jobconf file is: 
<configuration> 
<property><name>stream.addenvironment</name><value>"dumbo_mrbase_class=dumbo.backends.common.MapRedBase dumbo_jk_class=dumbo.backends.common.JoinKey dumbo_runinfo_class=dumbo.backends.streaming.StreamingRunInfo   
PYTHONPATH=common.pyc:typedbytes-0.3.6-py2.6.egg"</value></property> 


<property><name>stream.map.input</name><value>typedbytes</value></property> 
<property><name>stream.reduce.input</name><value>typedbytes</value></property> 
<property><name>stream.map.output</name><value>typedbytes</value></property> 
<property><name>stream.reduce.output</name><value>typedbytes</value></property> 
<property><name>mapred.job.name</name><value>group_clusters.py   
(1/1)</value></property> 
</configuration> 

Is it possible that the value I set for stream.addenvironment in the 
job configuration file is overwritten by the call 
jobConf._set("stream.addenvironment",addTaskEnvironment_); 
in StreamJob.setJobConf()?

I'm using CDH3B.


Thanks 


Jeremy
