Ted Yu commented on FLINK-5629:
-------------------------------
RandomAccessFile#length() may throw IOE.
raf is used in the following code path where DefaultFileRegion is not involved:
{code}
} else {
lastContentFuture = ctx.writeAndFlush(new HttpChunkedInput(new
ChunkedFile(raf, 0, fileLength, 8192)),
{code}
It is good practice to close RandomAccessFile in all code paths.
> Unclosed RandomAccessFile in StaticFileServerHandler#respondAsLeader()
