Last updated on SEPTEMBER 08, 2017

Applies to:

Big Data Appliance Integrated Software - Version 4.5.0 and later
Linux x86-64

Symptoms

After the Mammoth upgrade Step 2 reboot the kernel is not upgraded.


For example using a Mammoth 4.5 to 4.8 upgrade, after the Step 2 reboot, the kernel remains at the 4.5 version 2.6.39-400.294.1.el6uek.x86_64 rather than being upgraded to the 4.8 version 4.1.12-94.el6uek.x86_64.

For example during 4.5 to 4.8 upgrade after the Step 2 reboot "uname -a" output shows: 

b) The JDK is successfully upgraded.

c) The file /root/BDA_REBOOT_SUCCEEDED is present as it should be.

d) There is sufficient space in /boot as viewed with "df -h /boot".
