So, the server start/restart operation exceeds the default 60 sec. timeout value set for the Ambari web UI..

Increase the server start/restart timeout value to at least 120 seconds, by changing the value of the following property:

server.startup.web.timeout=120

in

ambari.properties

then, try the start or restart operation again..

BUG-63623

After restarting Hive Server Interactive (HSI); old, calculated values based on earlier YARN configs are applied for HSI restart. This happens because RESTART HSI does not automatically recalculate the HSI configs.

User will have to manually trigger the HSI/LLAP re-calculation, using any one of the following actions:

(try each workaround in the following order)

  • Turn off HSI, then turn on HSI manually, OR,

  • Re-select a queue from the drop-down menu. OR,

  • Adjust the number of LLAP nodes.(this slider is only editable if the selected queue is named "llap" and the queue is at root-level), OR

  • Adjust the Maximum Total Concurrent Queries value, if necessary.
