Example 1 with RetryOnStartFailureService

use of co.cask.cdap.common.service.RetryOnStartFailureService in project cdap by caskdata.

the class DistributedLogFramework method createService.

@Override
protected Service createService(Set<Integer> partitions) {
    Map<String, LogPipelineSpecification<AppenderContext>> specs = new LogPipelineLoader(cConf).load(contextProvider);

            }
        }, retryStrategy));
