Can't wait to tell my boss we need to load a deprecated function to make our little hbase work...... Looks like it's time to move back to good ole dependable DB2... Too much uncertainty with hadoop... MapR, Cloudera and Hortonworks..... Seems to me that these companies are trying to be the Uber of data... Complete unequivocal failures. Rehash of the internet bubble after Y2k.... Going back to IBM.
