问题
I am using Pentaho for reading a very large file. 11GB.
The process is sometime crashing with out of memory exception, and sometimes it will just say process killed.
I am running the job on a machine with 12GB, and giving the process 8 GB.
Is there a way to run the Text File Input step with some configuration to use less memory? maybe use the disk more?
Thanks!

Open up spoon.sh/bat or pan/kettle .sh or .bat and change the -Xmx figure. Search for JAVAMAXMEM Even though you have spare memory unless java is allowed to use it it wont work. although to be fair in your example above i can't really see why/how it would be consuming much memory anyway!
