ETL with Hadoop - Big Data Made Easy: A Working Guide to the Complete Hadoop Toolset - page 309

To be able to demonstrate the Designer perspective, which is displayed by default, previously I had created the
ETL job called “tmr1.” This allows me to explain the Open Studio interface features. Open Studio for Big Data opens to
the main interface, shown in Figure 10-26 . The searchable palette on the right provides a list of dragable modules. For
instance, searching for “thdfs” and “tpig” provides a list of HDFS and Pig modules. The center of the interface contains
the current open jobs as tabs; in this case, tmr1, the Pig-based Map Reduce job I had created previously, is shown. The
arrows indicate data flows or conditions, while the icons represent functional modules, such as tHDFSConnection_1.
Because I have already successfully run tmr1, it shows some extra information about how the fast data rows were
processed (i.e., one row in 166.12 seconds).
