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 trust store at this location  "<DBeaver_Install_Location>/jre/lib/security /cacerts " , you don't need to specify both  of those parameters in the URL.

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.

HIVE

1. When doing multi table joins, except the last ( right most ) table, other tables are buffered in the reducers. So to have less memory footprint on reducers, largest tables should be the last one as it is not buffered but streamed to reducers.   For Impala , it is different. 2.  You can filter the unwanted records within the join itself. SELECT  a.*,   b. * FROM a LEFT OUTER JOIN b ON ( a.key=b.key  AND  b.name= 'Tim'   AND a .name= 'Kim' ) 3. Joins are left associative. So execution happens from left to right and the result of joins is  fed into next join operation. 4. To find the value of variable     set hive.execution.engine 5. To find values of all variables set  6. If you want to pass different hive configuration settings in hive shell, you can use --hiveconf. For example hive --hiveconf hivi.optimize.sort.dynamic.partition=true --hiveconf hive.exec.dynamic.partition.mode=nonstrict 7.  In case you accidentally drop the p
