----------------------------------
Summary: CleanerChore shouldn't leak IOException for failed delete
of non-empty directory
Key: HBASE-7465
URL: https://issues.apache.org/jira/browse/HBASE-7465
Project: HBase
Issue Type: Bug
Components: master
Affects Versions: 0.96.0, 0.94.4
Reporter: Jesse Yates
Assignee: Jesse Yates
Fix For: 0.96.0, 0.94.4
CleanerChore has the following lines:
{code}
// if all the children have been deleted, then we should try to delete this
directory. However,
// don't do so recursively so we don't delete files that have been added
since we checked.
return canDeleteThis ? fs.delete(toCheck, false) : false;
{code}
has a race condition where the directory can have a file added underneath of it
between being determined 'ok to delete' and not. As the comment mentions, we
don't do a recursive delete to avoid deleting those files. However, the
non-recursive delete of the directory throws an IOException.
