I'm playing around with a small Hadoop 3.1.1 cluster and I have applied Ozone 0.3.0-alpha to all the nodes. The hadoop-ozone-datanode-plugin-0.3.0-alpha.jar and hadoop-ozone-filesystem-0.3.0-alpha.jar have been added to the classpath and I can start and init SCM, OM and create volumes, buckets and add new keys with values. But when I try to use Ozone as the default file system ( as described here https://hadoop.apache.org/ozone/docs/0.3.0-alpha/ozonefs.html ) starting the name nodes fails with the following message:
2019-02-12 17:32:48,467 ERROR org.apache.hadoop.hdfs.server.namenode.NameNode: Failed to start namenode. java.lang.IllegalArgumentException: Invalid URI for NameNode address (check fs.defaultFS): o3fs://internal.address:9864/volume/bucket is not of scheme 'hdfs'. I have also tried Hadoop 3.2.0 and I encountered the same error message. Anyone have a clue what the cause might be? /Pontus
