HDFS Storage System
Chukwa uses HDFS as the storage system.
HDFs is designed to support large file storage and small concurrent high-speed write scenarios, and the log system is the opposite, it needs to support high concurrency low-rate write and a large number of small file storage.
Note that small files that are written directly to HDFs are not visible until the file is closed, and HDFs does not support file
