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:

Thanks.
