TEZ log missing

[LLBian <li...@126.com>]

Hello,all:
     
      【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)

    I  found this "org.apache.hadoop.hive.ql.exec.tez.TezProcessor.initializeAndRunProcessor.run(TezProcessor.java:149)", In my hive source code:
----------------------------------------------------------------------------------------------
line 147: MRTaskReporter mrReporter = new MRTaskReporter(getContext));
line 148: rpoc.init(mrReporter, input, outputs);
line 149: rpoc.run();
--------------------------------------------------------------------------------------------------
      I added a LOG message before line 149:
 "LOG.info("-----TezProcessor.run(), rpoc is " + rpoc.getClass());"
 it wasn't printed in container log. why?(hive.compute.splits.in.am=true) I can not understand，should I change yarn log configurations?

   Any reply will be appreciated.

Thankyou & Best Regards.
