----------------------------
Summary: Group should not ignore the ZNOAUTH error in creating the
parent path for the group
Key: MESOS-958
URL: https://issues.apache.org/jira/browse/MESOS-958
Project: Mesos
Issue Type: Bug
Reporter: Yan Xu
Assignee: Yan Xu
Fix For: 0.18.0
We previously assumed that we had to proceed when facing ZNOAUTH in creating
the parent path of the group because the parent could already exist.
See comment:
https://github.com/apache/mesos/blob/b73591057d06c79f241ca81737bcb61e56963e2b/src/zookeeper/group.cpp#L407
This was because we used to recursively create the parent path without checking
its existence first so if the path already existed and we didn't have ACLs to
create its child we got ZNOAUTH.
Now we do an [existence
check|https://github.com/apache/mesos/blob/b73591057d06c79f241ca81737bcb61e56963e2b/src/zookeeper/zookeeper.cpp#L548]
first in that logic so the assumption no longer holds.
The result of it is that the nonretryable error is not exposed until
Group::join is called, which then complains about the base path not exist. This
can be confusing and we don't know why the base path wasn't created.
We should instead abort the group in the face of ZNOAUTH error when creating
the group base path.
