Lz0 is enabled now what?

[#1]

So I've enabled lz0 compression as per HortonWorks guide... I've got 120TB of storage capacity so far and a defacto replication factor of 3. My data usage is at 75% and my manager is starting to wonder if lz0 can be used to compress the the file system "a la windows" where the file system is compressed but the data is accessible "as per usual" through the dfs path?

Any hint would be greatly appreciated....

I went through the tutorial above for HDP 2.4.2 without success...

I changed the to the right directory location, still the same error though 😕

[#4]

Is there no actual step by step guide on how to do that... Been searching for weeks, nothing concrete so far.

Changed YARN Java heap size from 1Gb to 4... it still dies?
