@Sandeep Kumar Try doing a hard refresh of the storm UI page "CRTL+SHIFT+R" (Chrome)

if it doesn't fix do clear the cookies from browser and retry.

Hi Sandeep, thanks for your kind response. I have tried doing the both options that you have suggested me. But still, i'm facing the same issue. I have killed the existing storm topology (from CLI) and submitted a new topology after that. Even the new topology does seem to be loading. Issue still persists.

Can you Please help me with another way-out for this issue.

Regards,

Sandeep Kumar

@Sandeep Kumar Can you please try opening ui in another browser?

[#5]

Sandeep, I have tried with multiple browsers as well. Issue is still replicating. May i know where can i find the storm logs in the unix server (ambari). They may help me understand what's the issue is.

log will be in the machine where UI daemon is running. path would be /var/log/storm/ui.log (default)

@Sandeep Kumar is it possible that you're running into https://issues.apache.org/jira/browse/AMBARI-22518, it's always worth checking release notes for latest fixes. https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.1.0/bk_ambari-release-notes/content/ambari_reln.... Ambari 2.6.2 is out so it may be worth upgrading to the latest.
