Storm Logviewer - download full log

[Oleksandr Sokalskyi1 <Ol...@epam.com>]

Hi All,


I'm using Apache Storm with logviewer configured on all nodes. I'm able to view logs from <host>:8000/log?file=nimbus.log


But if I try to download full log ('Download Full Log' link which direct to <host>:8000/download/nimbus.log). Server respond with '500 Internal Server Error?'.


>From logviewr log:

I tried googling but with no result. ?Can you advice how to fix this?

Storm version - 0.9.4?


Thanks.
