JVM options not taken into consideration, spark-submit of java program -


using spark-submit i'm launching java program. i'm setting java arguments jvm not taken account. i'm trying specify max/min heap free ratio.

however, though arguments present (based on visualvm), memory graph shows don't affect running program.

here command i'm launching:

"/usr/jdk1.8.0_131/bin/java" "-xmx4096m" "-dspark.driver.extrajavaoptions=-xx:minheapfreeratio=30 -xx:maxheapfreeratio=30 -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005" "-dspark.executor.extrajavaoptions=-xx:minheapfreeratio=30 -xx:maxheapfreeratio=30" "-xx:minheapfreeratio=30" "-xx:maxheapfreeratio=30"

as can see, i've tried setting arguments on driver, executor , java command.

here arguments visualvm: enter image description here

and here graph:enter image description here

to clear, i'm trying improve "unused" heap size.

when starting program these arguments (outside of spark), behaves correctly.

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 ...
