> Verify we're using netty .so epolling on linux post HBASE-18271
> ---------------------------------------------------------------
>
> Key: HBASE-18588
> URL: https://issues.apache.org/jira/browse/HBASE-18588
> Project: HBase
> Issue Type: Task
> Components: test
> Affects Versions: 2.0.0
> Reporter: stack
> Assignee: stack
> Fix For: 2.0.0
>
>
> This is a task to verify that indeed we are using .so native epoll on linux.
> This task is probably unnecessary since we'd fail on the linux build box if
> this was not in place but verify that our relocation is indeed finding the
> native code. Assigned myself.
