[jira] [Commented] (DRILL-4979) Make dataport configurable

["Uwe L. Korn (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DRILL-4979?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15614793#comment-15614793 ] 

Uwe L. Korn commented on DRILL-4979:
------------------------------------

Implementation-wise it seems like the only point where the {{+1}} is actually hardcoded is in {{exec/java-exec/src/main/java/org/apache/drill/exec/rpc/data/DataConnectionCreator.java:62}}, i.e. {{int port = server.bind(partialEndpoint.getControlPort() + 1, allowPortHunting)}}. Therefore a fix for this could be to introduce a new configuration option {{drill.exec.rpc.bit.server.dataport}} and use this if set, otherwise default back to {{controlport + 1}}.

> Currently the dataport of a Drillbit is fixed to +1 on the control port. In a dynamic execution environment like Apache Mesos+Aurora, each port is allocated by the scheduler and then passed on to the application process. There is no possibility or guarantee to allocate two consecutive ports. Therefore, to run Drill in this environment, the dataport of the drillbit also needs to configurable by the scheduler.
