Aleksandr Shulman created HBASE-7579:
----------------------------------------
Summary: HTableDescriptor equals method fails is results are
returned in a different order
Key: HBASE-7579
URL: https://issues.apache.org/jira/browse/HBASE-7579
Project: HBase
Issue Type: Bug
Components: Admin
Reporter: Aleksandr Shulman
Priority: Minor
HTableDescriptor's compareTo function compares a set of HColumnDescriptors
against another set of HColumnDescriptors. It iterates through both, relying on
the fact that they will be in the same order.
In my testing, I may have seen this issue come up, so I decided to fix it.
It's a straightforward fix. I convert the sets into a hashset for O(1) lookups
(at least in theory), then I check that all items in the first set are found in
the second.
Since the sizes are the same, we know that if all elements showed up in the
second set, then they must be equal.
