# 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).

# 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 libraries required for hive compilation/execution can be controlled by:
# export HIVE_AUX_JARS_PATH=

# HIVE Log Directory can be controlled by the following and ensure it exists on the filesystem:
# export HIVE_LOG_DIR=

# The hive service being invoked (beeline 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 [ "$SERVICE" = "beeline" ]; then
#   if [ -z "$DEBUG" ]; then
#     export HADOOP_CLIENT_OPTS="$HADOOP_CLIENT_OPTS -Xms10m -XX:MaxHeapFreeRatio=40 -XX:MinHeapFreeRatio=15 -XX:+UseG1GC -XX:-UseGCOverheadLimit"
#   else
#     export HADOOP_CLIENT_OPTS="$HADOOP_CLIENT_OPTS -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.

# if [ "$SERVICE" = "metastore" ]; then
#   export HADOOP_HEAPSIZE=1024
#   export HADOOP_CLIENT_OPTS="$HADOOP_CLIENT_OPTS -Dhive.log.dir=$HIVE_LOG_DIR -Dhive.log.file=hive$SERVICE.log \
#     -Dlog4j.configurationFile=$HIVE_CONF_DIR/hive-log4j2.properties -XX:+UseG1GC \
#     -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=$HIVE_LOG_DIR \
#     -Xlog:gc*=info:file=$HIVE_LOG_DIR/gc-${SERVICE}-%p-%t.log:time,uptime,level,tags:filecount=5,filesize=16M"
# fi
#
# if [ "$SERVICE" = "hiveserver2" ]; then
#   export HADOOP_HEAPSIZE=1024
