Enabling LLAP in HDP-2.6

I got following errors when tried to enable Hive LLAP via ambari:

 

2017-10-30 14:37:31,925 - LLAP app 'llap0' deployment unsuccessful.
Traceback (most recent call last):

Command failed after 1 tries

In my case the solution was:
num_retries_for_checking_llap_status from 10 to 30
