Sylvain Lebresne updated CASSANDRA-2321:
----------------------------------------
Attachment: 0001-Don-t-allow-normal-query-on-counter-CF.patch
Actually, having getString() return hexString is the right thing to do, because
internally counters are bytes and getString is used by sstable2json in
particular.
The problem however is that it is not disallowed to query a counter CF with
non-counter operation. Attaching a patch to correct this. This is a bigger
patch that one would hope because ThriftValidation doesn't help. So the patch
does a bunch of refactoring to allow what it must do. As a side node, the
refactoring makes it more efficient (We don't revalidate the column family for
each mutation of a batch_mutate).
Btw, stress.py has no support for counters, but stress.java has it.
> Counter column values shows in hex values. Need to show it in string value.
