> We noticed a possible resource leak [here|https://github.com/apache/hadoop/blob/1f1a1ef52df896a2b66b16f5bbc17aa39b1a1dd7/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/EditLogFileOutputStream.java#L91].
If an I/O error occurs at line 91, rp remains open since the exception isn't caught locally,
and there is no way for any caller to close the RandomAccessFile.
>  I'll submit a pull request to fix it.
