We've found an issue in DN where the root filesystem is getting filled after running the cluster for a while. This is because after importing a container successfully, datanode is not deleting the container tar.gz file from working directory(/tmp by default). More details in https://issues.apache.org/jira/browse/HDDS-1417 Thanks Sandeep On Tue, Apr 9, 2019 at 3:55 AM Ajay Kumar <ajay.ku...@hortonworks.com<mailto:ajay.ku...@hortonworks.com>> wrote: Hi all, We have created the first release candidate (RC0) for Apache Hadoop Ozone 0.4.0-alpha.
