Row Key : 00001 Column : (Column Qualifier:Version:Value) Features of HBASE HBase data stores consist of one or more tables, which are indexed by row keys. Data is stored in rows with columns, and rows can have multiple versions. By default, data versioning for rows is implemented with time stamps. Columns are grouped into column families, which must be defined upfront during table creation. Column families are stored together on disk, which is why HBase is referred to as a column-oriented datastore New features of HBASE check now In addition... HBase is a distributed data store, which leverages a network-attached cluster of low-cost commodity servers to store and persist data. HBase architecture is a little trick to know. Region Servers... RegionServers are the software p...

While it is one of the loops in Python. The specialty is it never be false. You already know that in my previous post I have shared For Loop in Python . The for loop can be false. I am giving here one best example: print("Help! My computer doesn't work!") while True: print("Does the computer make any sounds (fans, etc.)") choice = input(" or show any lights? (y/n):") In the above logic, while is always true. When in input user can give 'Y/N'. if choice == 'n': # The computer does not have power print (" Do not show lights") if choice == 'y': # It is power plugged in print ("show lights") So, while is always true. Based on input the while loop works. Python is having the below list of Keywords. Pythons Reserved Words The Python reserved words are: and, exec, not, assert, finally, or, break, for, pass, class, form, print, continue, global, raise, def, if,...
