Hello
I wanted to test Ozone so I installed CDP 7.1.1 and setup OzoneFS according to the not-so-accurate documentation.
The FS itself seems to work. I am able to use hdfs commands to see files in ozone, create directories and upload local files. However, YARN does not work so well with Ozone.
If I try to create jobHistory directory or install MapReduce framework jars from the Yarn CM Menu then it fails and says it does not recognize the OzoneFS jars. I get:
java.lang.RuntimeException: java.lang.ClassNotFoundException: Class org.apache.hadoop.fs.ozone.OzoneFileSystem not found
I tried adding the jar (hadoop-ozone-filesystem-lib-current-0.5.0.7.1.1.0-565.jar) to MR application classpath and YARN application classpath. I also tried to add as the value of mapreduce.application.classpath in mapred-site.xml,
But none of them made it recognize the class and work.
Did anyone have success running YARN over Ozone ? What am I missing ?
Thank you
Guy
