Sorry, a detailed description: I wanna know how many files a datanode can hold, so there is only one datanode in my cluster. When the datanode save 14million files, the cluster can't work, and the datanode has used all of it's MEM(32G), the namenode's MEM is OK.

This max number of HDFS files should be no smaller than max files a datanode can hold. Please feel free to correct me because I'm just beginning learning hadoop.
