LLAP failed to start - wrong Python version for scripts

Can not start Hive LLAP:

File "<unknown>", line 1, in template
ambari_jinja2.exceptions.TemplateSyntaxError: Unexpected end of template. Jinja was looking for the following tags: 'endif'. The innermost block that needs to be closed is 'if'.

Maybe this issue is related to the wrong python version?

OS: Ubuntu 14.04.5

# /usr/bin/python -V
Python 2.7.6

@Gunar Mueller

Looks like you made some changes in the llap java options from Ambari UI specially inside the Jinja template specially related to llap java option from ambari UI and by mistake you removed the "endif" string from the if ...else blok of Jinja template.

Please see in the ambari UI if you can revert back the config changes and then try again... or compare the two versions of Hive configs from ambari UI.

@Jay Kumar SenSharma

You are right. I changed the <LLAP app java opts> and deleted {% endif %}.

Thanks
