----------------------------------
Summary: Ozone: ozone server should create missing metadata
directory if it has permission to
Key: HDFS-12053
URL: https://issues.apache.org/jira/browse/HDFS-12053
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ozone
Reporter: Weiwei Yang
Assignee: Weiwei Yang
Priority: Minor
Datanode state machine right now simple fails if container metadata directory
is missing, it is better to create the directory if it has permission to. This
is extremely useful at a fresh setup, usually we set
{{ozone.container.metadata.dirs}} to be under same parent of
{{dfs.datanode.data.dir}}. E.g
* /hadoop/hdfs/data
* /hadoop/hdfs/scm
if I don't pre-setup /hadoop/hdfs/scm/repository, ozone could not be started.
