Nemon Lou created HADOOP-10613: ---------------------------------- Summary: Potential Resource Leaks in FileSystem.CACHE Key: HADOOP-10613 URL: https://issues.apache.org/jira/browse/HADOOP-10613 Project: Hadoop Common Issue Type: Bug Components: fs Affects Versions: 2.4.0 Reporter: Nemon Lou
There is no size limit of the hashmap in FileSystem.CACHE, which can cause a potential memory leak. If every time i use a new UGI object to invoke FileSystem.get(conf) and never invoke FileSystem's close method,this issue will raise. If there is a size limit of the hashmap or changing fileSystem instances to soft reference,then user's code don't need to consider too much about the cache leak issues. -- This message was sent by Atlassian JIRA (v6.2#6252)
