hue Upgrade Document

First, identify our two installation packages:

  • (This package can also be downloaded from our git repository, and I'll send you a link)

Then stop hue's service at the CDH's management interface:

1, Enter hue

2, Select an instance

3, select Hue Server

4, select Action -> Stop this Hue Server

After stopping the hue service, go into the shell and start installing kerberos:

1, unzip

2, Enter, open krb5.conf

3, Modify kdc, admin_server

  kdc = master
  admin_server = master

4, add two new files: master and slaves (which store the host name of the primary node and the host name of the child node, respectively):

master input:


slaves input:


5, enter / usr/java/jdk1.7.0_71/jre/lib/security/under this path, add the

local_policy.jar  US_export_policy.jar

These two jar packages are moved to this path

6, enter the huetool folder and execute the script (scripts only need to be executed on the primary node, recommended on the master node):


7, prompt when installing:

Initializing database '/var/kerberos/krb5kdc/principal' for realm 'SUNMNET.COM',
master key name 'K/M@SUNMNET.COM'
You will be prompted for the database Master Password.
It is important that you NOT FORGET this password.
Enter KDC database master key:
Re-enter KDC database master key to verify:

Input password:


8, Start Kerberos in CDH:

Enter the management interface of CDH -> Management -> Security -> Enable Kerberos Service

First page:

  • First line selection: MIT KDC

  • Fill in the second line: master

  • Line 3: SUNMNET.COM

  • Line 4: aes256-cts

  • Line 5 Selection: 5 days

Second page:

  • First line: root/admin@SUNMNET.COM

  • Line 2: sunmnet123 (Here's the password we just set, recommended sunmnet123)

Third page:

  • Check

Fourth page:

  • Full Default

Page 5:

  • Full Default

Then the Kerberos installation is complete

Test Kerberos

First input:

hadoop fs -ls /

It will make an error, and then we enter:

kinit hdfs

We will be prompted to enter the password:


Then enter:

hadoop fs -ls /

You won't make a mistake at this time

2, modify the default configuration:
