    Hello ,

    Python script generate_logs.py is not generating log files. When I tried to run the script command prompt did not return to normal. Any clues ?

    Exact same issue. Tutorial says ” When the log file has been generated, a timestamp will appear, and the command prompt will return to normal ([root@Sandbox \~]\#). It may take several seconds to generate the log file.” but I do not see command prompt returning to NORMAL! Any help at all?

    Update: Nothing wrong with the tutorial, just very very slow. If I stop the python script in 5 mins, I get approx 100 rows with HCatalog. If I leave the python script running for almost an hour, I get 500 rows with HCatalog. Sadly, the eventlog has 250,000+ rows!!! So either leave the python script for a day or two or try this: http://kzhendev.wordpress.com/2014/04/06/apache-flume-get-logs-out-of-rabbitmq-and-into-hdfs/
