- # 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:
- # export HIVE_AUX_JARS_PATH=
