Actor Model

Actor model is a programming paradigm which models any software system as composed of actors which communicate with each other by sending messages (no reply hence non-blocking). Message is the only means of communication with external world for these actors. Messages are queued at each actor and are processed in sequence.  This avoids the need for synchronization in object oriented world and avoids the need of costly locks and in turn deadlocks.  In this manner Actor Model is supposed to meet the demands of high performance parallel processing systems of today.

Joins - Not always very obvious ( Following example uses Hive ). create table x_temp ( name string, p_date int  ) insert into x_temp(name,p_date) values ('x1',20181025),('x2', 20181026), ('x3',20181027) create table y_temp ( name string, s_date int  ) insert into y_temp(name,s_date) values ('x1',20181025),('x2', 20181026), ('x3',20181027) create table z_temp ( name string, p_date int, s_date int ) insert into z_temp(name,p_date,s_date) values ('z1','20181025','20181025') select x.*, y.* from x_temp x, y_temp y, z_temp z  where x.p_date != z.p_date and  y.s_date != z.s_date) generates 4 records... x.name,x.p_date,y.name,y.s_date x2, 20181026, x2, 20181026 x3, 20181027, x2, 20181026 x2, 20181026, x3, 20181027 x3, 20181027, x3, 20181027 select x.*, y.* from x_temp x, y_temp y, z_temp z  where x.p_date != z.p_date or  y.s_date != z.s_date) generates 8 records x.name,x.p_date,y....

DBeaver

Recently I used this tool for connecting to Hive via Knox gateway.  Good thing about this tool is that it automatically downloads the driver and configures it. That  is a pain in tools like Squirrel.  It also makes a JDBC connection to Hive.  Below is how the HOST and JDBC URL settings look like : HOST : <KNOX_HOST>:8443/;ssl=true;transportMode=http;httpPath=gateway/<topology>/hive JDBC URL :  jdbc:hive2://<KNOX_HOST>:8443/;ssl=true;transportMode=http;httpPath=gateway/<topology>/hive What I noticed on my setup was that if you keep the default port which 10000 and you set it to 8443 , it does not work. So you have to keep it blank.  That may be specific to my setup. Also you might notice that ssl=true but there are  no  sslTrustStore= < Path to the “.jks” file in the NiFi node > ;trustStorePassword= < TrustStore Password>  parameters. The reason is if you import the gateway cert  into the trus...
