本文档详细介绍了Hive的安装过程，包括上传和解压缩软件包，修改配置文件如hive-env.sh和hive-site.xml，解决Jline包版本冲突问题以及处理MySQL权限设置。在配置过程中，需要将MySQL的JAR包复制到lib路径，并替换hadoop中的jline.2.12.jar以确保版本一致性。

# 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=/root/app/hadoop-2.6.4 #hadoop路径

# 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=

vi hive-site.xml
