             Summary: pip error
                 Key: TOREE-477
                 URL: https://issues.apache.org/jira/browse/TOREE-477
             Project: TOREE
          Issue Type: Bug
            Reporter: Nitin Pasumarthy


It looks like the TOREE-97 issue -- support for Spark Yarn was closed without definitive solution (or something went wrong on the way). Toree does support it, but it won't work if a user doesn't add manually in their kernel.json definition, the env vars for {{HADOOP_CONF_DIR}}. Without that env var, Spark doesn't know what to do with the option {{--master=yarn}} (set in {{__TOREE_SPARK_OPTS__}}). It would be desirable to have it by default.
Probably this is not the nicest way to solve the problem, because it  just hard codes more vars into the JSON file -- ideally it would be nice to have an interface to add or remove env vars from those files, however, {{HADOOP_CONF_DIR}}  and {{SPARK_CONF_DIR}}  look basic to be exported. Even for an Spark Standalone deployment, {{HADOOP_CONF_DIR}} won't hurt.  So, here it goes our 2 cents to improve a bit the situation.

I cloned the TOREE-97 into TOREE-438 to sign this issue.
