Hue failed to start on machine which has Python 2.7.5 and HDP2.5, requires python 2.6.

[#1]

Hi Team,

I have installed and configured HUE on cent-OS 7 machine, which is also a MASTER NODE in my hadoop cluster and this machine has python 2.7.5 available. Machine is up and running with HDP2.5 and I have installed HUE as a separate service because HDP2.5 was not having prebuild HUE service at the time of Hadoop Installation.

I have followed the below HUE Installation guide.

https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.4.2/bk_installing_manually_book/content/ch_inst...

Now when I start HUE as '/etc/init.d/hue start' command it fails with following error.

[root@vmhgm2 bin]# /etc/init.d/hue status ● hue.service - SYSV: Hue web server Loaded: loaded (/etc/rc.d/init.d/hue) Active: failed (Result: exit-code) since Wed 2017-03-08 10:54:46 UTC; 11s ago Docs: man:systemd-sysv-generator(8) Process: 59405 ExecStart=/etc/rc.d/init.d/hue start (code=exited, status=127) Mar 08 10:54:46 vmhgm2 hue[59405]: /usr/bin/env: python2.6: No such file or directory Mar 08 10:54:46 vmhgm2 runuser[59407]: pam_unix(runuser:session): session closed for user hue Mar 08 10:54:46 vmhgm2 runuser[59417]: pam_unix(runuser:session): session opened for user hue by (uid=0) Mar 08 10:54:46 vmhgm2 hue[59405]: Starting hue: /usr/bin/env: python2.6: No such file or directory Mar 08 10:54:46 vmhgm2 runuser[59417]: pam_unix(runuser:session): session closed for user hue Mar 08 10:54:46 vmhgm2 hue[59405]: [FAILED] Mar 08 10:54:46 vmhgm2 systemd[1]: hue.service: control process exited, code=exited status=127 Mar 08 10:54:46 vmhgm2 systemd[1]: Failed to start SYSV: Hue web server.

Please see below link, HUE not supported on CentOS7 (Although you can have Python 2.6.6 or higher installed on the supported OS.)

1. Before You Begin
Before you begin your Hadoop installation, you must meet the following requirements.
Note: Hue can only connect to one Hadoop cluster.
    Ensure that you are using an operating system that supports Hue.
    The following 64-bit operating systems support Hue:
        CentOS 6
        Oracle Linux 6
        Red Hat Enterprise Linux (RHEL) 6
        SUSE Linux Enterprise Server  SLES
