Deep understanding of cloud storage and cloud computing-HDFS Design Principles

HDFS is the foundation in the entire hadoop framework. HDFS provides massive unstructured data storage and provides APIs for file creation, deletion, reading, and writing, developers only need to operate on the tree structure composed of a directory. At the beginning of its design, HDFS has considered the following as

"Go" cleans up intermediate storage data for Kylin (HDFS & HBase Tables)

http://blog.csdn.net/jiangshouzhuang/article/details/51290399Kylin generates intermediate data on HDFS during the cube creation process. Also, when we execute purge/drop/merge on cube, some hbase tables may remain in hbase, and the tables are no longer queried, although Kylin does some automatic garbage collection, but it may not overwrite all aspects, So we need to be able to do some cleanup work for offline stor
