Upgrade to BDA V4.4 Replaces a Higher Installed UEK Kernel Version with the Default from the V4.4 Mammoth Bundle
Last updated on FEBRUARY 11, 2016

You will encounter the issue here if prior to BDA V4.4 upgrade, the UEK Kernel on the cluster was updated to a version that is higher than the default provided by the Mammoth V4.4 Software Bundle.
The UEK Kernel on BDA V4.4 by default is: 2.6.39-400.264.1.el6uek.x86_64. If the UEK Kernel on the cluster prior to V4.4 upgrade was updated to a version higher than this, for example, 2.6.39-400.264.5.el6uek.x86_64 the V4.4 Mammoth bundle will restore the Kernel to the default on V4.4.
