hi everyone,
I am getting following error when i am trying to start kernel for javascript.
**Failed to run command:
[u'/usr/local/lib/python2.7/dist-packages', u'eclair:org.eclairjs.nashorn.JavascriptInterpreter', u'eclair', u'--nosparkcontext', u'--profile', u'/run/user/1002/jupyter/kernel-8db32e1c-a195-4198-8ce5-a5cd7adaecd9.json']
PATH='/usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/lib/jvm/java-8-oracle/bin:/usr/lib/jvm/java-8-oracle/db/bin:/usr/lib/jvm/java-8-oracle/jre/bin'
with kwargs:
{'cwd': u'/home/stack/.local/share/jupyter/kernels/eclair', 'stdin': -1, 'preexec_fn': <function <lambda> at 0x7f441d4a0aa0>, 'stderr': None, 'stdout': None}**
but its' working fine when i'm creating kernel for python.
when i use it in code to instantiate sparkcontext object it's throwing following error.
