Configurando o Apache Hue

Observação

Ignore esta etapa para clusters do Big Data Service com a versão 3.0.7 ou mais recente, uma vez que o Apache Hue já está instalado e configurado nos nós do cluster.

Esta seção detalhes do procedimento que você segue para configurar o Apache Hue para um cluster inseguro ou seguro.

Configurando o Apache Hue para um Cluster Não Seguro

Crie um usuário hue para o Apache Hue executando os seguintes comandos:

sudo useradd -u 54336 hue
sudo chown -R hue:hue /usr/local/hue
sudo su - hdfs -c "hdfs dfs -mkdir /user/hue"
sudo su - hdfs -c "hdfs dfs -chown hue:hadoop /user/hue"
sudo su - hdfs -c "hdfs dfs -chmod 755 /user/hue"
sudo mysql -u root

Execute as seguintes instruções na interface MySQL:

create database desktop;
grant all privileges on *.* to 'hue'@'localhost ';
grant all on hue.* to 'hue'@'localhost';
alter user 'hue'@'localhost' identified by 'secretpassword';
flush privileges;
exit

Edite o arquivo hue.ini e atualize as seções dos serviços que você deseja usar com o Hue.

sudo vim /usr/local/hue/desktop/conf/hue.ini

MySQL

[[database]]
# Database engine is typically one of:
# postgresql_psycopg2, mysql, sqlite3 or oracle.

engine=mysql
host=localhost
port=3306
user=hue
password=secretpassword
name=desktop

HDFS

[[hdfs_clusters]]
	[[[default]]]
	# Enter the filesystem uri
	fs_defaultfs=hdfs://<master_node_fully_qualified_hostname>:8020

	# Use WebHdfs/HttpFs as the communication mechanism.
	# Domain should be the NameNode or HttpFs host.
	# Default port is 14000 for HttpFs.

     webhdfs_url=http://<master_node_fully_qualified_hostname>:50070/webhdfs/v1

YARN

[[yarn_clusters]]

    [[[default]]]
     # Enter the host on which you are running the ResourceManager
     resourcemanager_host=<master_node_fully_qualified_hostname>    

     # The port where the ResourceManager IPC listens on
     resourcemanager_port=8050

     # URL of the ResourceManager API
     resourcemanager_api_url=http://<master_node_fully_qualified_hostname>:8088

     # Whether to submit jobs to this cluster
     submit_to=True

     # URL of the ProxyServer API
     proxy_api_url=http://<master_node_fully_qualified_hostname>:8088

     # URL of the HistoryServer API
     history_server_api_url=http://<utility_node_fully_qualified_hostname>:19888

     # URL of the spark history server
     spark_history_server_url=http://<master_node_fully_qualified_hostname>:18081

Oozie

[liboozie]
# The URL where the Oozie service runs on.
oozie_url=http://<utility_node_fully_qualified_hostname>:11000/oozie

Hive

[beeswax]

# Host where HiveServer2 is running.
hive_server_host=<utility_node_fully_qualified_hostname>

# Http thrift port for HiveServer2.
hive_server_http_port=10002

# Use SASL framework to establish connection to host.
use_sasl=true

HBase

[hbase]

# Comma-separated list of HBase Thrift server 1 for clusters in the format of '(name|host:port)'.
hbase_clusters=(Cluster|<master_node_fully_qualified_hostname>:9090)

A lista de serviços que não devem ser carregados na inicialização do servidor

[desktop]

# Comma separated list of apps to not load at server startup.
# e.g.: pig,zookeeper
app_blacklist=impala,security

Abra um novo arquivo, nomeie-o como pseudo-distributed.ini e, em seguida, adicione as seguintes seções:

sudo vim /usr/local/hue/desktop/conf/pseudo-distributed.ini
[beeswax]

max_number_of_sessions=-1
[[hdfs_clusters]]
    # HA support by using HttpFs

    [[[default]]]
      # Enter the filesystem uri
      fs_defaultfs=hdfs://<master_node_fully_qualified _hostname>:8020

      webhdfs_url=http://<master_node_fully_qualified_hostname>:50070/webhdfs/v1
[[yarn_clusters]]

resourcemanager_api_url=http://<master_node_fully_qualified_hostname>:8088
8088

Atualize as permissões do Hive.

sudo chmod -R 777 /etc/hive
sudo su - hue
cd /usr/local/hue/build/env/bin/
./hue syncdb --noinput
./hue migrate
nohup ./hue runcpserver &
