 # Set Hive and Hadoop environment variables here. These variables can be used
 # to control the execution of Hive. It should be used by admins to configure
 # the Hive installation (so that users do not have to set environment variables
 # or set command line parameters to get correct behavior).

 # The hive service being invoked (CLI/HWI etc.) is available via the environment
 # variable SERVICE


 # Hive Client memory usage can be an issue if a large number of clients
 # are running at the same time. The flags below have been useful in
 # reducing memory usage:
 #
 # if [ "$SERVICE" = "cli" ]; then
 #   if [ -z "$DEBUG" ]; then
 #     export HADOOP_OPTS="$HADOOP_OPTS -XX:NewRatio=12 -Xms10m -XX:MaxHeapFreeRatio=40 -XX:MinHeapFreeRatio=15 -XX:+UseParNewGC -XX:-UseGCOverheadLimit"
 #   else
 #     export HADOOP_OPTS="$HADOOP_OPTS -XX:NewRatio=12 -Xms10m -XX:MaxHeapFreeRatio=40 -XX:MinHeapFreeRatio=15 -XX:-UseGCOverheadLimit"
 #   fi
 # fi

 # The heap size of the jvm stared by hive shell script can be controlled via:
 #
 # export HADOOP_HEAPSIZE=1024
 #
 # Larger heap size may be required when running queries over large number of files or partitions.
 # By default hive shell scripts use a heap size of 256 (MB).  Larger heap size would also be
 # appropriate for hive server (hwi etc).


 # Set HADOOP_HOME to point to a specific hadoop install directory
 # HADOOP_HOME=${bin}/../../hadoop

 # Hive Configuration Directory can be controlled by:
 # export HIVE_CONF_DIR=

 # Folder containing extra ibraries required for hive compilation/execution can be controlled by:
