> We noticed a possible resource leak [here|https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/FSImageFormatProtobuf.java#L271]. If an I/O error occurs at line [273|https://github.com/apache/hadoop/blob/06a5d3437f68546207f18d23fe527895920c756a/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/FSImageFormatProtobuf.java#L273] or [277|https://github.com/apache/hadoop/blob/06a5d3437f68546207f18d23fe527895920c756a/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/FSImageFormatProtobuf.java#L277], {{fin}} remains open since the exception isn't caught locally, and there is no way for any caller to close the FileInputStream
> I'll submit a pull request to fix it.
