Not all the procedures from apoc are loaded although the jar file is in the plugins directory

Neo4j Graph Platform Procedures & APOC
1

I am using the latest version, locally downloaded, with the jar files in the plugin folder.
All the procedures are not loaded.

For example, all the functions apoc.map.* are not seen, although they are supposed to be in the list (https://neo4j.com/docs/apoc/current/overview/apoc.map/)

Also, I see a lot of errors in the debug.log file, ex.:

Failed to load apoc.util.hdfs.HDFSUtils from plugin jar /Users/.../neo4j/plugins/apoc-5.21.2-core.jar: java.lang.NoClassDefFoundError: org/apache/hadoop/fs/FSDataOutputStream

Not sure how much reliable is this library..

@syolbe

Is there any detail on Neo4j version and APOC version other than 'latest'?

As to

Failed to load apoc.util.hdfs.HDFSUtils from plugin jar /Users/.../neo4j/plugins/apoc-5.21.2-core.jar: java.lang.NoClassDefFoundError: org/apache/hadoop/fs/FSDataOutputStream

this is expected and are described as WARN statments and should be the cause
