I am trying to run PFPGrowth but I keep receiving this Java heap space error at

Hi!
I am trying to convert a dataset from text to SeqFormat.
The file is inside txtData directory and is 532 MB.
I am using a virtual machine with ubuntu with 1500MB of RAM assigned.
I got a heap space error when I execute the following command:
mahout seqdirectory -i ./txtData/ -o ./seqData
98 matches
