Hi,
Whenever I reply to the mailing list, I get the following error reply and
can't send the reply. I'm using Gmail. When I send the same mail from the
same Gmail account to my non-Gmail account, I succeed.
I searched for the solution at Google with the keyword "552 552 spam score
(5.8) exceeded threshold (state 18)." and knew that some people experienced
the same error. But I couldn't find the solution.
Who can tell me how to solve this problem?

Thanks, Andy
I understood HBASE-1295 is inter-cluster replication and HBASE-2357 is
intra-cluster replication. I hope the configuration and administration will
be easy unlike RDBMS. I also hope multi-master replication feature will be
added in the future, which is stated in Bigtable paper as follows:
"We are in the process of implementing several additional Bigtable features,
such as support for secondary indices and infrastructure for building
crossdata-center replicated Bigtables with multiple master replicas."

Others have followed up on the central question, which is about
durability, and have pointed out that the text is misleading.
However more generally regarding the question "Does HBase do in-memory
replication of rows?":
HBase will have a replication feature in the next release independent of
HDFS layer data block replication:
HBASE-1295: https://issues.apache.org/jira/browse/HBASE-1295
This is cluster-to-cluster replication, at the HBase layer, and at a finer
granularity than the row.
HBase may also in the future evolve an optional extension to the BigTable
architecture:
HBASE-2357: https://issues.apache.org/jira/browse/HBASE-2357
and this I think also meets the definition of in-memory replication. While
HBASE-2357 talks about availability, I see this as a means for offering
higher read scalability for some use cases that can accept a relaxation of
HBase's ACID guarantees.
So an answer to "Does HBase do in-memory replication of rows?" is also in
part: Actually we might do that, independent of providing durability by
other means.
