Spark/Scala kernel failing on Jupyter due to Java error -


i've been using spark/scala kernel on jupyter (i'm not sure version/how check since it's not listed in jupyter kernelspec list).

all of sudden, stopped working. poking around bit, i've found error preventing kernel initiating:

exception in thread "main" java.lang.unsupportedclassversionerror: com/typesafe/config/configmergeable : unsupported major.minor version 52.0

i've seen several threads trying address issue (1, 2, 3, 4), don't follow them @ / how apply suggested solutions situation.

it appears there's sort of version mismatch somewhere inside how kernel's working, don't know how figure out mismatch / how fix it. i've looked @ following, don't see (or know how diagnose, really) inconsistency:

printenv | grep "java" # java_home=/usr/lib/jvm/java-7-openjdk-amd64  java -version # java version "1.7.0_131" # openjdk runtime environment (icedtea 2.6.9) (7u131-2.6.9-0ubuntu0.14.04.2) # openjdk 64-bit server vm (build 24.131-b00, mixed mode)  javac -version # javac 1.7.0_131

this being run on remote machine, have terminal access diagnose / fix problem.

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
