             Summary: Potential resource leak due to unclosed RandomAccessFile in TaskManagerLogHandler#
                 Key: FLINK-4573
                 URL: https://issues.apache.org/jira/browse/FLINK-4573
             Project: Flink
          Issue Type: Bug
            Reporter: Ted Yu
            Priority: Minor


{code}
                                                try {
                                                        raf = new RandomAccessFile(file, "r");
                                                } catch (FileNotFoundException e) {
                                                        display(ctx, request, "Displaying TaskManager log failed.");
                                                        LOG.error("Displaying TaskManager log failed.", e);
                                                        return;
                                                }
                                                long fileLength = raf.length();
                                                final FileChannel fc = raf.getChannel();
{code}
If length() throws IOException, raf would be left unclosed.
