Subject Re: Sharing RDDS across applications and users
Date Fri, 28 Oct 2016 08:28:32 GMT
Thanks all for your advice.

As I understand in layman's term if I had two applications running
successfully where app 2 was dependent on app 1 I would finish app 1, store
the results in HDFS and the app 2 starts reading the results from HDFS and
work on it.

Using  Alluxio or others replaces HDFS with in-memory storage where app 2
can pick up app1 results from memory or even SSD and do the work.

Actually I am surprised why Spark has not incorporated this type of memory
as temporary storage.
