>            Reporter: Amar Kamat
>            Assignee: Amar Kamat
>            Priority: Blocker
>             Fix For: 0.19.0
>         Attachments: HADOOP-4190-v3.patch, HADOOP-4190-v4.patch, HADOOP-4190-v5.patch,
HADOOP-4190-v6.1.patch, HADOOP-4190-v6.patch
> 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.
