1. Installation and configuration: http://gethue.com/hadoop-hue-3-on-hdp-installation-tutorial/
2. List of third-party components that Hue relies on:
   Https://github.com/cloudera/hue#development-prerequisites

Installing dependent third-party components for installation

-y install gcc-c++ asciidoc cyrus-sasl-devel cyrus-sasl-gssapi krb5-devel libxml2-devel libxslt-devel mysql-devel openldap-devel python-devel sqlite-devel openssl-devel gmp-devel

Manually install Ant and maven

In the list of third-party components that Hue relies on, it also includes Ant and Maven, and it is recommended that you manually download the appropriate release package to unzip the installation, and then configure the environment variables Ant_home and maven_home and the path

Installation

Enter the extracted directory and execute:

make install

Sometimes the make install fails because a third-party-dependent component is missing, which can be cleaned and then reinstalled:

make clean&&rm -rf /usr/local/hue&&make install

In particular, it is important to make sure that the network is unblocked during the build process, because MAVEN downloads the dependent jar packages in the build.

Configuration modification Hue.ini

The specific configuration is described in detail in the reference document given at the beginning, with only a few additional highlights:

Configure Hue:

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

Use:

:%s/localhost/your-master-node/gc

Find the place to replace the localhost. If it is a # #注释掉的项目需要去掉注释使其生效.

If you are installing HDP, you will want to find app_blacklist specifically, modified to:

app_blacklist=impala,security

Because HDP does not support these two modules.

Also need to modify is Secret_key, at the back of the random write a string can.

secret_key=3rT*[email protected]

Create a Hue user

It is recommended that you create a full-time user for Hue and set the/usr/local/hue group and owner to the hue User:

groupadd hueuseradd -g hue huechown -R hue:hue /usr/local/hue

Start

Start:

sudo -u hue nohup /usr/local/hue/build/env/bin/supervisor &

Stop it:

pkill -U hue

FAQ Hue Page Tip: The app won ' t work without a running Livy Spark Server

Livy server is the Rest API service for Spark, official documentation:
Https://github.com/cloudera/hue/tree/master/apps/spark/java

We can use:

sudo -u hue nohup /usr/local/hue/build/env/bin/hue livy_server &

To start it, but before you start it you need to know its version dependency on Spark. Livy server in Hue3.9 needs Spark 1.4, and HDP2.3 installs spark 1.3, which means that if you install HDP, you can't use spark on hue now, to avoid the Hue page escalation: Spark the app won ' t Work without a running Livy Spark Server error, we can disable the Spark module and edit the Hue.ini file as well:

app_blacklist=impala,security,spark

Hue page error:/wsgiserver.py line 1196 in Communicatereq.respond ()

If you open the Hue page:
Traceback (most recent):
File "/usr/local/hue/desktop/core/src/desktop/lib/wsgiserver.py", line 1196, in communicate
Req.respond ()
It is likely that the previous use of RPM to install the old version of Hue did not completely uninstall the reason, in addition to check whether the relevant files have been completely removed, it is important to delete the previously established hue users and user groups .
