I am not able to use enclosedby and escapedby arguments in Teradata hadoop connector. I get the following error when I pass these arguments. here I am trying to set enclosedby with a double quote and escapedby with forward slash. The error goes away when I remove the enclosedby and escapedby arguments.

I have a Hive table that is too big for my Teradata database, but if I can exclude some of the columns, it should be OK. Since I don't want to have a duplicate copy of the table with fewer columns on my hadoop server I have two choices for import: 1) use a view to filter out the columns or 2) use a query to filter out the columns.

HI, we have a sqoop job that exports data to Teradata hourly. Sometimes job fails with untranslatable character error. We would like to know, if there is any Java Function to check if the string is translatable by teradata. This is of higher priority. Please let us know, if there are any questions.

The Analytical Ecosystem can be quite complex. It usually consists of multiple managed servers containing instances of databases, ETL servers, infrastructure services and application servers. Monitoring and managing applications in this environment can be a very challenging task. Knowing at any moment what is the state of your hardware, how your applications are doing, how many jobs have finished successfully, how many failed and why have they failed are the types of questions database administrators typically ask themselves. Now with the addition of Hadoop infrastructure components within an ecosystem, monitoring has become even harder. Unity Ecosystem Manager helps users to answer those questions and perform and necessary maintenance tasks.

Hi Masters,
This is a Hadoop/Teradata scenario. I'm looking for advise for a data migration from Hadoop to Teradata. The source data is supposed to be coming in form of delimited flat files. What are my best options for migrating data with best performance.

Teradata Studio provides a Smart Loader for Hadoop feature that allows users to transfer data from Teradata to Hadoop, Hadoop to Teradata, and Hadoop to Aster. When transfering between Teradata and Hadoop, the Hadoop Smart Loader uses the Teradata Connector for Hadoop MapReduce Java classes as the underlying technology for data movement.

Hadoop systems [1], sometimes called Map Reduce, can coexist with the Teradata Data Warehouse allowing each subsystem to be used for its core strength when solving business problems. Integrating the Teradata Database with Hadoop turns out to be straight forward using existing Teradata utilities and SQL capabilities. There are a few options for directly integrating data from a Hadoop Distributed File System (HDFS) with a Teradata Enterprise Data Warehouse (EDW), including using SQL and Fastload. This document focuses on using a Table Function UDF to both access and load HDFS data into the Teradata EDW. In our examples, there is historical data already in Teradata EDW, presumably derived from HDFS for trend analysis. We will show examples where the Table Function UDF approach is used to perform inserts or joins from HDFS with the data warehouse.
