Running a job when moving a file in the hdfs directory (hadoop)

Question

I want to run a task (hive or pig or oozie..etc) when the file is transferred to a specific directory (by tray) in the Hadoop distributed file system. Is it possible?

Answer 1

This is possible indirectly. Oozie does not support data availability triggers. You need to set up a periodic flow with a certain frequency and add data availability as an additional condition.

This is a fairly common question about Oozi, unfortunately the documentation is poor.
