Michael Brown updated KUDU-2375:
--------------------------------
Description:
When tables with decimals are added in 1.7.0, a downgrade from 1.7.0 to 1.6
results in a dcheck when 1.6 starts and Kudu isn't usable in its downgraded
version.

was:
A downgrade from 1.7.0 to 1.6 results in a dcheck when 1.6 starts. I see the
same dcheck on both 1.6.0 and 1.6.x. A "revert" back to 1.7.0 makes the problem
go away.
Although the symptom is in 1.6, I've filed this against 1.7.0 assuming the
backward incompatibility was not intended.
