The all counters is on the same row?

By the way, did you guys handle the hbase bug that when an increment is
sent to region server and fails it still does it but throws an exception to
the client which causes it to do that increment again?

Well, I increment counters where the row key is a keyword and the qualifier
is a country code, and in the post increment region observer I increment an
"all countries" aggregative counter. These counters are divided to families
such as daily, weekly, hourly etc.
So I get the family map to know which aggregative counter should I
increment, then I piggyback onto the Result the "all countries" current
count.

Can you tell us what operation you perform on the returned family map ?


Thanks

I'm using Increment.getFamilyMap in a postIncrement Observer.

I'm running with HBase 0.94.2.

The reason was that Increment was serialized differently (compared to

other mutations).

In trunk that is no longer an issue, since the serialization logic is

no

longer part of the object to be serialized.

Subject: HBASE-7114 Increment does not extend Mutation but probably

should


Hi,

I want to get opinion on whether we should proceed with HBASE-7114

'Increment does not extend Mutation but probably should' in trunk.


Is anyone using Increment.setWriteToWAL or Increment.getFamilyMap ?

For Increment.setWriteToWAL, are you using the Increment returned ?


Your feedback would be appreciated.
