hi, there, I feel a little confused about the *cache* in spark. first, is there any way to *customize the cached RDD name*, it's not convenient for me when looking at the storage page, there are the kind of RDD in the RDD Name column, I hope to make it as my customized name, kinds of 'rdd 1', 'rrd of map', 'rdd of groupby' and so on.
second, can some one tell me what exactly the '*Fraction Cached*' mean under the hood? great thanks -- *--------------------------------------* a spark lover, a quant, a developer and a good man. http://github.com/litaotao
