RE: [cloudsuite] data analytics

Hello,

Seems that you ran out of memory and your system is doing garbage collection 
all the time.
You should try adjusting the number of concurrent map processes and/or the 
amount of memory 
allocated to each process.


Regards,
Djordje

Subject: [cloudsuite] data analytics

Hi,

I'm trying to install the data analytic benchmark and I'm having trouble with 
the last step (testclassifier). I keep on getting an error in configuring 
object, the full log is attached. The conf files are also attached in case the 
error is in one of them.
