hadoop - Logical / Virtual data store in HDFS -

-

is there way creating logical / virtual data store in hdfs ?

say want create catagory product. if query on product hadoop go product catagory not perticular hdfs.

so want query based on catagories.

use hive. feel can achieve through hive , it'l more convenient. hive provides warehousing capabilities on top of running hadoop cluster. create db particular product , store data related product tables of db. not this, hive provides sql interface data stored in warehouse enables query data of interest directly writing simple queries without having write complex mr jobs or lengthy programs.

(i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
