question about drill storage plugin

[Tan Sheng 谈晟 <ta...@saicmotor.com>]

Hi,

We are a Chinese company(Shanghai Automotive Industry Corporation(Group)), and we extending drill to support more storage such as ES, Cassandra. The code base we are referring to is: https://github.com/kevinlynx/drill-storage-http it is a sample storage plugin for http service. The question is while we use this plugin, it can not work in parallel, we build two dedicate http service for testing, suppose there will be two minor fragment run on two drillbits. But it always one. And we try to copy code snippet from Hbase plugin and Kudu plugin which seem to be related with parallelize, but does not work. In HttpGroupScan.java the parameter “endpoints” of function “applyAssignments” is always one, is it the root cause, and how to set it?







谢谢，
谈晟@数据业务部
