[jira] [Created] (HDDS-1680) Create missing parent directories
during the creation of HddsVolume dirs
Elek, Marton created HDDS-1680:
----------------------------------
Summary: Create missing parent directories during the creation of HddsVolume dirs
Key: HDDS-1680
URL: https://issues.apache.org/jira/browse/HDDS-1680
Project: Hadoop Distributed Data Store
Issue Type: Bug
Reporter: Elek, Marton
Assignee: Elek, Marton
I started to execute all the unit tests continuously (in kubernetes with argo workflow).
Until now I got the following failures (number of failures / unit test name):
```
1 org.apache.hadoop.fs.ozone.contract.ITestOzoneContractMkdir
1 org.apache.hadoop.fs.ozone.contract.ITestOzoneContractRename
3 org.apache.hadoop.hdds.scm.container.placement.algorithms.TestSCMContainerPlacementRackAware
31 org.apache.hadoop.ozone.container.common.TestDatanodeStateMachine
31 org.apache.hadoop.ozone.container.common.volume.TestVolumeSet
1 org.apache.hadoop.ozone.freon.TestDataValidateWithSafeByteOperations
```
TestVolumeSet is also failed locally:

The problem here is that the parent directory of the volume dir is missing. I propose to use hddsRootDir.mkdirs() instead of hddsRootDir.mkdir() which creates the missing parent directories.
