I've run some tests with some real and some synthetic parquet data with nested 
columns with and without the hive metastore on our Spark 1.5, 1.6 and 2.0 
versions. I haven't seen any unexpected performance surprises, except that 
Spark 2.0 now does schema inference across all files in a partitioned parquet 
metastore table. Granted, you aren't using a metastore table, but maybe Spark 
does that for partitioned non-metastore tables as well.

@Michael,
I answered in Jira and could repeat here.
I think that my problem is unrelated to Hive, because I'm using
read.parquet method.
I also attached some VisualVM snapshots to SPARK-16321 (I think I should
merge both issues)
And code profiling suggest bottleneck when reading parquet file.

I wonder if there are any other benchmarks related to parquet performance.

[Marcin Tustin]

I refer to Maciej Bryński's (mac...@brynski.pl) emails of 29 and 30 June
2016 to this list. He said that his benchmarking suggested that Spark 2.0
was slower than 1.6.

I'm wondering if that was ever investigated, and if so if the speed is back
up, or not.

SHA and MD5 sums match for all binaries. Docs look fine this time
around. Built and ran `dev/run-tests` with Java 7 on a linux machine.

No blocker bugs on JIRA and the only critical bug with target as 2.0.0
is SPARK-16633, which doesn't look like a release blocker. I also
checked issues which are marked as Critical affecting version 2.0.0
and the only other ones that seem applicable are SPARK-15703 and
SPARK-16334. Both of them don't look like blockers to me.

Thanks
Shivaram

Snappy initialization issue, spark assembly jar missing snappy classes?

[Eugene Morozov]

Greetings!

We're reading input files with newApiHadoopFile that is configured with
multiline split. Everything's fine, besides
https://issues.apache.org/jira/browse/MAPREDUCE-6549. It looks like the
issue is fixed, but within hadoop 2.7.2. Which means we have to download
spark without hadoop and provide custom version of it. Now we use
spark-1.6.1.

It mostly fine, there is doc how to configure, spark started, but when I
use it it gives me nasty exception about snappy cannot be initialized. I
tried few things - update snappy version inside hadoop, package snappy into
my own application jar, but it works only when I literally copy
snappy-java.jar classes into spark-assembly-1.6.1-hadoop2.2.0.jar. It seems
working for now, but I dislike this approach, because I simply cannot know
what else won't work tomorrow.
It looks like I can just turn off snappy, but I want it, I believe it makes
sense to compress data shuffled and stored around.

Could you suggest any way besides copying these classes inside assembled
spark jar file?
