Subject Re: Parquet MR version
Date Tue, 09 Jan 2018 23:26:29 GMT
Support for byte buffers aka "PARQUET-77: ByteBuffer use in read and 
write paths" is included both to 1.8.2 and 1.9.0 parquet-mr. Based on 
the following discussion 

Drill should move to the released version of parquet-mr. I'll file a 
JIRA and summarize my findings.

Thank you,

abstraction is used on top of byte arrays (e.g., ByteBuffer) so that Drill will not need to
use a private Parquet branch. I guess the key is to figure out why such an approach was not
followed in the first place.

As far as I can tell both 1.8.2 and 1.9.0 have fixes from the 1.8.1-drill-r0 patch. Will the
community prefer 1.9.0 over 1.8.2 even if 1.9.0 may introduce some incompatibilities?
