Summary: Support ozone dist-start-stitching on openbsd/osx
Key: HDDS-280
URL: https://issues.apache.org/jira/browse/HDDS-280
Project: Hadoop Distributed Data Store
Issue Type: Bug
Reporter: Elek, Marton
{quote}Ozone is creating a symlink during the dist process.
Using the "ozone" directory as a destination name all the docker-based
acceptance tests and docker-compose files are more simple as they don't need to
have the version information in the path.
But to keep the version specific folder name in the tar file we create a
symbolic link during the tar creation. With the symbolic link and the
'–dereference' tar argument we can create the tar file which includes a
versioned directory (ozone-0.2.1) but we can use the a dist directory without
the version in the name (hadoop-dist/target/ozone).
{quote}
This is the description of the current
dev-support/bin/ozone-dist-tar-stitching. [~aw] in a comment for HDDS-276
pointed to the problem that some bsd variants don't support the dereference
command line options of the ln command.
The main reason to use this approach is to get a simplified destination name
without the version (hadoop-dist/target/ozone instead of
hadoop-dist/target/ozone-0.2.1). It simplifies the docker-compose based
environments and acceptance tests, therefore I prefer to keep the simplified
destination name.
The issue is the tar file creation, if and only if we need the version number
in the name of the root directory inside of the tar.
Possible solutions:
# Use cp target/ozone target/ozone-0.2.1 + tar. It's simple but more slow and
requires more space.
# Do the tar distribution from docker all the time in case of 'dereference' is
not supported. Not very convenient
# Accept that tar will contain ozone directory and not ozone-0.2.1. This is
the more simple and can be improved with an additional VERSION file in the root
of the distribution.
# (+1) Use hadoop-dist/target/ozone-0.2.1 instead of hadoop-dist/target/ozone.
This is more complex for the docker based testing as we need the explicit names
in the compose files (volume: ../../../hadoop-dist/target/ozone-0.2.1). The
structure is more complex with using version in the directory name.
Please comment your preference.
