[jira] [Updated] (HIVE-12497) Remove HADOOP_CLIENT_OPTS from hive script

["Prasanth Jayachandran (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HIVE-12497?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Prasanth Jayachandran updated HIVE-12497:
-----------------------------------------
    Attachment: HIVE-12497.1.patch

Removing HADOOP_CLIENT_OPTS, we will get errors like 
"ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console." during startup. This is because hadoop is still using old log4j1.x. This really does not matter as it is being thrown by "hadoop version" command. What really matters is hive saying successful initialization of logging like below
"Logging initialized using configuration in file:/work/configs/hive/pseudo-distributed/hive-log4j2.xml"
