>
> In TaskLog.java, Temporary Index File is created by following code.
> {code}
> BufferedOutputStream bos =
> new BufferedOutputStream(
> SecureIOUtils.createForWrite(tmpIndexFile, 0644));
> DataOutputStream dos = new DataOutputStream(bos);
> {code}
> The code is surrounded by try-finally so if some Exception/ERROR is thrown
> between constructing bos and dos, temporary file is not cleaned up.
> I met the situation that when a thread ran, OOM was thrown after bos created
> and temporary file is not cleaned up. At different time, another thread
> executed same logic and fail because of FileAlreadyExistsException.
