Mahadev konar updated AMBARI-1256:
----------------------------------
Description:
Currently disks_info column is 2000 characters long.
This was not big enough to fit all the mount points detected (they had 40+
mount points on their hosts).
We made this disks_info column size to be 10000 to workaround this issue.
Ensure that upgrade supports performing schema alteration on an existing
installation.
