Hello, I am trying to run multiple hive queries in parallel by submitting them through a map-reduce job. More specifically, I have a map-only hadoop streaming job where each mapper runs a shell script that does two things -- 1) parses input lines obtained via streaming; and 2) submits a very simple hive query (via hive -e ...) with parameters computed from step-1.
Now, when I run the streaming job, the mappers seem to be stuck and I don't know what is going on. When I looked on resource manager web UI, I don't see any new MR Jobs (triggered from the hive query). I am trying to understand this behavior. This may be a bad idea to begin with, and there may be better ways to accomplish the same task. However, I would like to understand the behavior of such a MR job. Any thoughts? Thank you, Shirish
