@Martin Tombs

I am yet to reproduce this error,

resource_management.core.exceptions.ExecutionFailed: Execution of 'ambari-python-wrap /usr/bin/hdp-select set mahout-client 2.6.4.0-91' returned 1. symlink target /usr/hdp/current/mahout-client for mahout 
already exists and it is not a symlink.

.

However sometimes it happens if instead of symlink there is a directory present.

So as a test workaround you might want to do this to see if it works:

# mv /usr/hdp/current/mahout-client  /usr/hdp/current/mahout-client_BAK

And if that is a symlink then do this
# unlink  /usr/hdp/current/mahout-client

.

After performing the above step please try installing Mahout again.
