It covers the usage of [[http://​spark.apache.org/​|Spark]] (MapReduce/​Hadoop alternative,​ but better) and HDFS (Hadoop filesystem).   * There is a **great course [[http://​ufal.mff.cuni.cz/​courses/​npfl102|Data intensive computing]]**,​ see the 2016 handouts if you missed the course.

-  * This course had used a special **DLRC (Demo LRC) cluster** (students had to login with ''​ssh -p 11422 ufallab.ms.mff.cuni.cz''​ and special NPFL102-only LDAP logins) with six virtual machines on one physical. During the years when NPFL102 is not taught (e.g. 2017), the DLRC cluster has just one virtual machine.
