Weird anomoly on HUE
I have a instance using chrome hitting the same HUE instance on the same cluster
in 1 tab I can run Impala queries but newer tabs cannot run any queries
Chrome Version 47.0.2526.73 (64-bit)
Sentry is not enabled
It may be a caching issue. So try changing the browser.
Like in my case it was working with hive but not with impala. Also i had disable the kerberos.
It may happen sometime when the kerberos is disabled from the cluster. So ensure following properties are changed on cloudera manager.
enableSecurity (Enable Kerberos Authentication) FALSE
dfs.datanode.address from 1004 (for Kerberos) to 50010 (default)
dfs.datanode.http.address from 1006 (for Kerberos) to 50075 (default)
Data Directory Permissions from 700 to 755
Kerberos Ticket Renewer: Delete role or stop role
olr Secure Authentication: Simple
Once Done. Try again same steps . else switch the browser, for eg change the browser to FireFox from chrome and try again.
