Amar Kamat commented on HADOOP-4190:
------------------------------------
The findbugs warning is because of the {{IOException}} which the parser ignores
while it tries to close the stream. Not something that I have introduced. Here
is a section from the patch that explains the warning
{code}
- }
+ } while ((line = reader.readLine())!= null);
} finally {
try { reader.close(); } catch (IOException ex) {}
{code}
> Changes to JobHistory makes it backward incompatible

> With HADOOP-3245, the job history format has changed. Every log line now ends
> with a '.' (dot). JobHistory's parser will consider a history line valid only
> if it ends in a dot
> Hence the new parser wont be able to parse old history files.
