3. 修改pom.xml文件
$ vim /opt/hue/maven/pom.xml
a.) 修改hadoop与spark版本
b.) 将hadoop-core修改为hadoop-common
c.) 将hadoop-test的版本改为1.2.1
d.) 将两个ThriftJobTrackerPlugin.java文件删除，分别在如下两个目录：
/usr/hdp/hue/desktop/libs/hadoop/java/src/main/java/org/apache/hadoop/thriftfs/ThriftJobTrackerPlugin.java
/usr/hdp/hue/desktop/libs/hadoop/java/src/main/java/org/apache/hadoop/mapred/ThriftJobTrackerPlugin.java
4. 编译
$ cd /opt/hue
$ make apps
5. 启动HUE服务
$ ./build/env/bin/supervisor
$ ps -aux|grep "hue"
$ kill -9 <端口号>
6. hue.ini 参数配置
$ vim /usr/hdp/hue/hue-3.10.0/desktop/conf/hue.ini
a.) [desktop] 配置
[desktop]
# Webserver listens on this address and port
http_host=xx.xx.xx.xx
http_port=8888
# Time zone name
time_zone=Asia/Shanghai
# Webserver runs as this user
server_user=hue
server_group=hue
# This should be the Hue admin and proxy user
default_user=hue
# This should be the hadoop cluster admin
default_hdfs_superuser=hdfs
[hadoop]
[[hdfs_clusters]]
[[[default]]]
# Enter the filesystem uri
# 如果HDFS没有配置 HA，则按照以下配置
fs_defaultfs=hdfs://xx.xx.xx.xx:8020 ## hadoop NameNode节点
# 如果HDFS配置了HA，则按照以下配置
fs_defaultfs=hdfs://mycluster ## 逻辑名称，与core-site.xml的fs_defaultfs保持一致
# NameNode logical name.
## logical_name=carmecluster
# Use WebHdfs/HttpFs as the communication mechanism.
# Domain should be the NameNode or HttpFs host.
# Default port is 14000 for HttpFs.
# 如果HDFS没有配置HA，则按照以下配置
webhdfs_url=http://xx.xx.xx.xx:50070/webhdfs/v1
# 如果HDFS配置HA，则HUE只能通过Hadoop-httpfs来访问HDFS; 手动安装Hadoop-httpfs：$ sudo yum install Hadoop-httpfs 启动Hadoop-httpfs服务：$ ./hadoop-httpfs start &
webhdfs_url=http://xx.xx.xx.xx:14000/webhdfs/v1
[[yarn_clusters]]
[[[default]]]
# Enter the host on which you are running the ResourceManager
resourcemanager_host=xx.xx.xx.xx
# The port where the ResourceManager IPC listens on
resourcemanager_port=8050
# Whether to submit jobs to this cluster
submit_to=True
# Resource Manager logical name (required for HA)
## logical_name=
# Change this if your YARN cluster is Kerberos-secured
## security_enabled=false
# URL of the ResourceManager API
resourcemanager_api_url=http://xx.xx.xx.xx:8088
# URL of the ProxyServer API
proxy_api_url=http://xx.xx.xx.xx:8088
# URL of the HistoryServer API
history_server_api_url=http://xx.xx.xx.xx:19888
# URL of the Spark History Server
## spark_history_server_url=http://localhost:18088
[[mapred_clusters]]
[[[default]]]
# Enter the host on which you are running the Hadoop JobTracker
jobtracker_host=xx.xx.xx.xx
# The port where the JobTracker IPC listens on
jobtracker_port=8021
# JobTracker logical name for HA
## logical_name=
# Thrift plug-in port for the JobTracker
thrift_port=9290
# Whether to submit jobs to this cluster
submit_to=False
[beeswax]
# Host where HiveServer2 is running.
# If Kerberos security is enabled, use fully-qualified domain name (FQDN).
hive_server_host=xx.xx.xx.xx
# Port where HiveServer2 Thrift server runs on.
hive_server_port=10000
# Hive configuration directory, where hive-site.xml is located
hive_conf_dir=/etc/hive/conf
# Timeout in seconds for thrift calls to Hive service
## server_conn_timeout=120
[hbase]
# Comma-separated list of HBase Thrift servers for clusters in the format of '(name|host:port)'.
# Use full hostname with security.
# If using Kerberos we assume GSSAPI SASL, not PLAIN.
hbase_clusters=(Cluster|xx.xx.xx.xx:9090)
# 如果连接hbase报错， 开启服务 $ nohup hbase thrift start &
[zookeeper]
[[clusters]]
[[[default]]]
# Zookeeper ensemble. Comma separated list of Host/Port.
# e.g. localhost:2181,localhost:2182,localhost:2183
host_ports=xx.xx.xx.xx:2181,xx.xx.xx.xx:2181,xx.xx.xx.xx:2181
[liboozie]
# The URL where the Oozie service runs on. This is required in order for
# users to submit jobs. Empty value disables the config check.
oozie_url=http://xx.xx.xx.xx:11000/oozie
b.) hadoop 相关配置
hdfs-site.xml 配置文件
core-site.xml 配置文件
如果HUE server在hadoop集群外，可以通过运行HttpFS server服务来访问HDFS. HttpFS服务仅需要一个开放
httpfs-site.xml 配置文件
c.) MapReduce 0.20（MR1）相关配置
HUE与JobTracker的通信是通过一个jar包，在mapreduce的lib文件夹下
如果JobTracker和HUE在同一个主机上，拷贝他
$ cd /usr/share/hue
$ cp desktop/libs/hadoop/java-lib/hue-plugins-*.jar /usr/lib/hadoop-0.20-mapreduce/lib
如果JobTracker 运行在不同的主机上，需要scp的Hue plugins jar 到JobTracker主机上
添加以下内容到mapred-site.xml配置文件，重启JobTracker
d.) Oozie 相关配置
oozie-site.xml配置
