Hello.

We have updated our CDH to 5.12.0 (from 5.7.0) and we are getting an error when Hue tries to load the table names in Impala query editor's sidebar.

The error shown in Hue: IndexOutOfBoundsException: Index: 11, Size: 11

And in the logs we are getting: 

==> runcpserver.log <==
[11/Aug/2017 14:17:36 +0200] access INFO 169.61.102.137 <username> - "POST /notebook/api/autocomplete/default HTTP/1.1"

From Hive's query editor, there is no issue. Also, if we refresh the list using the option "Invalidate all metadata and rebuild index", it shows the tables of that database, but when we switch to a different database and get back to the one that was working, we get the same message. 

Seems like we don't have any issue so far, the queries to Impala are running fine.

I feel like is an issue with the backend, but we couldn't find any more useful logs. The backend we are using is Oracle.

Do you have any tip or any clue about where this could come from?

Thank you. Regards!
