Johnny Zhang commented on BIGTOP-804:
-------------------------------------
The job all pass before #367, and they all run on 'ubuntu2'. I think slave
'ubuntu3' is a new added slave and have gcc pkg problem. From the code, it
seems it because package 'gcc' on ubuntu3 doesn't have field "description".
Since cannot login to the slave, cannot verify that.
