spark2 upgrade to 2.3.0 from 2.2.0 wont read or write snappy compressed parquet

This seems like a really simple case of wrong classpaths, and the wrong version of snappy being brought in, but I can't work out how/why!

I have an upgraded CDH5.14.2 (upgraded from 5.13.2), spark2.3.0(upgraded from 2.2.0 cloudera2, including the csd)

I do the following in a spark2-shell;

 

val df = spark.read.parquet("/inputdata/parquet/parquet*snappy*")

scala> df.show

 

And then just get the following error.... Any ideas how to debug/fix?

I did all this on an offline platform, but have now replicated on a fresh online install.

Help!

Re: spark2 upgrade to 2.3.0 from 2.2.0 wont read or write snappy compressed parquet

Hello,

 

Support fixed it for me :

 

The workaround for this is the following:  
 
copy snappy-java-1.1.4.jar to /opt/cloudera/parcels/SPARK2/lib/spark2/jars/ on each node where such executors are running. That can be downloaded from http://repo1.maven.org/maven2/org/xerial/snappy/snappy-java/1.1.4/snappy-java-1.1.4.jar.
 
Tested - confirmed working

Re: spark2 upgrade to 2.3.0 from 2.2.0 wont read or write snappy compressed parquet

Can you please confirm that you are using spark-shell as opposed to spark-submit

Re: spark2 upgrade to 2.3.0 from 2.2.0 wont read or write snappy compressed parquet

[ Edited ]

Hiya, yes it was spark2-shell.

The answer ChrisV has given is the fix, I'm so surprised the spark2.3.0 parcel didn't have this included!

Re: spark2 upgrade to 2.3.0 from 2.2.0 wont read or write snappy compressed parquet

Perfect! Thank you Chris, definitely solved. I thought I had caused it, but obviously based on this fix the spark2.3.0 parcel is just incomplete.

Re: spark2 upgrade to 2.3.0 from 2.2.0 wont read or write snappy compressed parquet

 

This works also without copying the jar to all nodes:

 

wget http://repo1.maven.org/maven2/org/xerial/snappy/snappy-java/1.1.4/snappy-java-1.1.4.jar
spark2-shell --jars snappy-java-1.1.4.jar --conf spark.executor.userClassPathFirst=true --conf spark.executor.extraClassPath=snappy-java-1.1.4.jar

 

Highlighted

According to https://www.cloudera.com/documentation/spark2/latest/topics/spark2_known_issues.html#KI_spark2_CDH-6..., the resolution is to upgrade to CDS 2.3 Release 3, which contains the fix.
