----------------------------------------

             Summary: Provide a way to set common environment variable between sqlline and Drillbit differently.
                 Key: DRILL-5685
                 URL: https://issues.apache.org/jira/browse/DRILL-5685
             Project: Apache Drill
          Issue Type: Task
            Reporter: Sorabh Hamirwasia
            Assignee: Sorabh Hamirwasia
             Fix For: 1.12.0


Drill has distrib-env.sh which is used to set any distribution specific environment consumed by both sqlline and Drillbit. These environment variables can be overridden by drill-env.sh. But there is no clean way to know if these scripts were sourced for Drillbit or for sqlline, currently all the variables will be set for both the scripts.
With this JIRA we will introduce a separated environment variable _DRILLBIT_CONTEXT_ which will only be set inside drillbit.sh. Based on this variable any script called later in the pipeline can make decision's to set/unset an environment variable or to set the common environment variable differently for sqlline and Drillbit.
