-----------------------------------
In more detail, the jetty HTTP server on each worker starts at the init phase.
The jetty can start slowly in a certain JVM,
> Late registration of Tajo workers

> Project: Tajo
> Issue Type: Bug
> Components: resource manager
> Reporter: Jihoon Son
> Fix For: 0.8-incubating
>
>
> The worker registration takes too much time.
> When I tested on an in-house cluster which consists of one master and 32
> workers, 31 workers are registered in about 2 minutes and one worker is
> failed to register.
> My guess from the log is that the failed worker does not receive any start
> messages.
