Explanation:The first, default strategy, is as follows: collectors write data to HDFS, and as soon as the HDFS write call returns success, report success to the agent, which advances its checkpoint state. 3. The __________ streams chunks of data to HDFS, and write data in temp filename with .chukwa suffix.
