Examples of co.cask.cdap.common.discovery.StickyEndpointStrategy

co.cask.cdap.common.discovery.StickyEndpointStrategy
An {@link EndpointStrategy} that will always return the same endpoint once it's pickeduntil the endpoint is no longer valid, then it'll pick another one. If multiple threads calling the {@link #pick()}} method at the same time, it's possible that they get different result if there was no endpoint being picked yet or the previously picked endpoint is no longer value. The pick will be eventually settled to the same one.

  protected final Connection getQueryClient() throws Exception {


    // this makes sure the Explore JDBC driver is loaded
    Class.forName(ExploreDriver.class.getName());


    Discoverable discoverable = new StickyEndpointStrategy(
      discoveryClient.discover(Constants.Service.EXPLORE_HTTP_USER_SERVICE)).pick();


    if (null == discoverable) {
      throw new IOException("Explore service could not be discovered.");
    }
