----------------------------
Summary: Potential null dereference in Utilities#clearWork()
Key: HIVE-8458
URL: https://issues.apache.org/jira/browse/HIVE-8458
Project: Hive
Issue Type: Bug
Reporter: Ted Yu
Priority: Minor
{code}
Path mapPath = getPlanPath(conf, MAP_PLAN_NAME);
Path reducePath = getPlanPath(conf, REDUCE_PLAN_NAME);
// if the plan path hasn't been initialized just return, nothing to clean.
if (mapPath == null && reducePath == null) {
return;
}
try {
FileSystem fs = mapPath.getFileSystem(conf);
{code}
If mapPath is null but reducePath is not null, getFileSystem() call would
produce NPE
