AWS DataSync

AWS DataSync is an online data transfer service that simplifies, automates, and accelerates copying large amounts of data to and from AWS storage services over the internet or AWS Direct Connect. DataSync can copy data between Network File System (NFS), Server Message Block (SMB) file servers, self-managed object storage, or AWS Snowcone, and Amazon Simple Storage Service (Amazon S3) buckets, Amazon Elastic File System (Amazon EFS) file systems, and Amazon FSx for Windows File Server file systems.

DataSync includes encryption and integrity validation to help make sure your data arrives securely, intact. DataSync does both full initial copies, and incremental transfers of changing data.

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...
