Sorry but we currently do not support Lustre either in parallel or to replace HDFS. You could try contacting hadoop.on.lustre@seagate.com as mentioned in the README

  Thanks for the answer. I heard about HAL (Hadoop Adapter On Lustre). It is exists? But i did not find it to download.

What else can I try to do?

I am not aware of this product or how to use it, sorry. Maybe someone else
can chime in if they have any knowledge about this.
