-------------------------------------
Summary: Spark tarball with binaries should have files owned by
uid 0
Key: SPARK-27513
URL: https://issues.apache.org/jira/browse/SPARK-27513
Project: Spark
Issue Type: Bug
Components: Build
Affects Versions: 2.4.1
Reporter: koert kuipers
Fix For: 3.0.0
currently the tarball is created in dev/make-distribution.sh like this:
{code:bash}
tar czf "spark-$VERSION-bin-$NAME.tgz" -C "$SPARK_HOME" "$TARDIR_NAME"
{code}
the problem with this is that if root unpacks this tarball the files are owned
by whatever the uid is of the person that created the tarball. this uid
probably doesnt exist or belongs to a different unrelated user. this is
unlikely to be what anyone wants.
for other users this problem doesnt exist since tar is now allowed to change
uid. so when they unpack the tarball the files are owned by them.
it is more typical to set the uid and gid to 0 for a tarball. that way when
root unpacks it the files are owned by root. so like this:
{code:bash}
tar czf "spark-$VERSION-bin-$NAME.tgz" --numeric-owner --owner=0 --group=0 -C
"$SPARK_HOME" "$TARDIR_NAME
{code}
