Subject TEZ log missing
Date Fri, 22 Jan 2016 06:08:15 GMT

      【My environment versions are :Hadoop 2.6.0 、hive 1.2.1、tez 0.7.0】
      Now I executed a HQL “select count(*) from h_im;”(h_im is an external table, hbase
table) in hive CLI, it throw exceptions:
    (I am sorry, I can not copy the error information here, because we use inner network,so
some information will be omitted)

      INFO [Dispatcher thread: Central] history.HistoryEventHandler: .... .....

    I  found this "",
In my hive source code:
line 147: MRTaskReporter mrReporter = new MRTaskReporter(getContext));
line 148: rpoc.init(mrReporter, input, outputs);
line 149:;
      I added a LOG message before line 149:
 "", rpoc is " + rpoc.getClass());"
 it wasn't printed in container log. why?( I can not understand,should
I change yarn log configurations?

   Any reply will be appreciated.

Thankyou & Best Regards.
