[jira] [Created] (YARN-11151) sensitive infor may leak due to crash

lujie created YARN-11151:
----------------------------

             Summary: sensitive infor may leak due to crash
                 Key: YARN-11151
                 URL: https://issues.apache.org/jira/browse/YARN-11151
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: lujie


we init LevelDBCacheTimelineStore and LeveldbTimelineStore like:

 
{code:java}
 try {
      localFS = FileSystem.getLocal(conf);
      if (!localFS.exists(dbPath)) {
        if (!localFS.mkdirs(dbPath)) {
          throw new IOException("Couldn't create directory for leveldb " +
              "timeline store " + dbPath);
        }
        localFS.setPermission(dbPath, LeveldbUtils.LEVELDB_DIR_UMASK);
      }
    } finally {
      IOUtils.cleanupWithLogger(LOG, localFS);
    } {code}
 

if node crash before setPermisson, then the permisison will be 755 forever

 

code should be like :
{code:java}
 try {
      localFS = FileSystem.getLocal(conf);
      if (!localFS.exists(dbPath)) {
        if (!localFS.mkdirs(dbPath)) {
          throw new IOException("Couldn't create directory for leveldb " +
              "timeline store " + dbPath);
        }
        
      }
         if (localFS.getStatus(dbPath).getPermmision().equlas(LeveldbUtils.LEVELDB_DIR_UMASK))){
       localFS.setPermission(dbPath, LeveldbUtils.LEVELDB_DIR_UMASK);}     } finally {
      IOUtils.cleanupWithLogger(LOG, localFS);
    } {code}
