---------------------------------------
Summary: Incorrect key name used for user info in pod annotation
in user guide example
Key: YUNIKORN-1831
URL: https://issues.apache.org/jira/browse/YUNIKORN-1831
Project: Apache YuniKorn
Issue Type: Improvement
Components: documentation
Reporter: Yongjun Zhang
[https://yunikorn.apache.org/docs/user_guide/usergroup_resolution/]
{code:java}
metadata:
annotations:
yunikorn.apache.org/user.info: "
{
username: \"yunikorn\",
groups: [
\"developers\",
\"devops\"
]
}" {code}
There are two problems with this example:
Without quoting the key name, yunikorn will complain
{code:java}
2023-06-22T21:48:56.243Z ERROR utils/utils.go:277 unable to
process user info annotation {"error": "invalid character 'u' looking for
beginning of object key
string"}github.com/apache/yunikorn-k8shim/pkg/common/utils.GetUserFromPod
/Users/yongjunzhang/code/yunikorn-vote/apache-yunikorn-1.3.0-src/k8shim/pkg/common/utils/utils.go:277github.com/apache/yunikorn-k8shim/pkg/appmgmt/general.getAppMetadata
{code}
After adding quote
{code:java}
metadata:
annotations:
yunikorn.apache.org/user.info: "
{
\"username\": \"yunikorn\",
\"groups\": [
\"developers\",
\"devops\"
]
}"{code}
I saw that user name still did not take effect, and found the code points to:
{code:java}
type UserGroupInformation struct {
// the user name
User string `protobuf:"bytes,1,opt,name=user,proto3" json:"user,omitempty"`
// the list of groups of the user, can be empty
Groups []string `protobuf:"bytes,2,rep,name=groups,proto3"
json:"groups,omitempty"`
{code}
Which means we should use "user" rather than "username"
