Xi Wang commented on AMBARI-6301:
---------------------------------
The solution:
If the user type in an exact value, then convert it to a range of numbers, and
turn into a range query to server.
For example, user enter 1.83 G, will pass a query to filter hosts with memory
from 1.825000 to 1.834999 GB.
For example, user enter 1.8 KB(MB), will pass a query to filter hosts with
memory from 1.75000 to 1.84999 KB(MB).
So Current behavior:
Say I have three hosts with RAM 1.83G on Hosts page.
Type in: 1.83 , Filtered Content: 3 hosts
Type in: 1.828 , Filtered Content: 3 hosts
Type in: 1.831 , Filtered Content: 3 hosts
Type in: 1.84 , Filtered Content: 0 hosts
Type in: 1.82 , Filtered Content: 0 hosts
Type in: 1.83k , Filtered Content: 0 hosts
Type in: 1.83m , Filtered Content: 0 hosts
> Hosts page: RAM filter not worked for exact match

> On hosts page, RAM filter not worked for exact match.
> If enter expressions such as '>1' or '<2' the filter works. But if enter
> exact match filter like '1.83' the filter does not work.
> Second problem is that usage of the filter is not intuitive. We should have
> hover text explaining how to use this filter.
