---------------------------------
Summary: Ensure git gc finished in ptest prep phase before copying
repo
Key: HIVE-18443
URL: https://issues.apache.org/jira/browse/HIVE-18443
Project: Hive
Issue Type: Sub-task
Components: Testing Infrastructure
Reporter: Adam Szita
Assignee: Adam Szita
In ptest's prep phase script first we checkout the latest Hive code from git,
and then we make copy of its contents (along .git folder) for that will serve
as Yetus' working directory.
In some cases we can see errors such as {{+ cp -R . ../yetus
cp: cannot stat ?./.git/gc.pid?: No such file or directory}}, e.g.
[here|https://issues.apache.org/jira/browse/HIVE-18372?focusedCommentId=16321507&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16321507]
This is caused by git running its gc feature in the background when our prep
script has already started copying. In cases where gc finishes while cp is
running, we'll get this error
