Elek, Marton commented on HDDS-481:
-----------------------------------
I think the problem is in the shading definition in hadoop-ozone/ozonefs/pom.xml
{code}
<include>com.google.guava:guava:jar</include>
<include>org.slf4j:slf4j-api:jar</include>
<include>com.google.protobuf:protobuf-java</include>
<include>com.nimbusds:nimbus-jose-jwt:jar</include>

<include>org.apache.ratis:ratis-grpc</include>
<include>org.rocksdb:rocksdbjni</include>
<include>org.apache.hadoop:hadoop-ozone-common</include>
{code}
the pattern of the lines is groupid:artifactId or groupid:artifactid:jar:*
(AFAIK). I think it will work with removing the ':jar' part from the lines.

> Key: HDDS-481
> URL: https://issues.apache.org/jira/browse/HDDS-481
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Components: Ozone Filesystem
> Reporter: Elek, Marton
> Assignee: Bharat Viswanadham
> Priority: Critical
>
> Ozonefs acceptance test contains only one simple command which is executed on
> an *ozone* node with ozone fs.
> Unfortunately the hdfs fs command doesn't work with ozone fs due to a missing
> class file.
> To test:
> {code}
> cd hadoop-dist/target/ozone-0.2.1-SNAPSHOT/compose/ozonefs
> docker-compose exec scm ozone sh volume create --user hadoop /vol1
> docker-compose exec scm ozone sh bucket create /vol1/bucket
> docker-compose exec hadooplast hdfs dfs -ls o3://bucket.vol1/
> {code}
> The result is:
