Good stuff Jimmy. A few comments below. Sorry I ramble at times. Read to the
end before reacting because I change my mind as I work through the patch. You
forgot to add RequestConverter?
src/main/java/org/apache/hadoop/hbase/HConstants.java
<https://reviews.apache.org/r/4629/#comment14787>
Should these be in here? Can they be elsewhere, as defines in
RegionClassProtocol?
src/main/java/org/apache/hadoop/hbase/catalog/MetaReader.java
<https://reviews.apache.org/r/4629/#comment14788>
I don't know how you get away with these removes but I'm glad to see them
go -- anything that shrinks this catalog package is good by me
src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
<https://reviews.apache.org/r/4629/#comment14789>
RegionClientProtocol is a bad name, no? Should it be just ClientProtocol
and AdminProtocol?
src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
<https://reviews.apache.org/r/4629/#comment14790>
this should be getClient? We're going to get a client for a table? Maybe
should be getTableClient?
src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
<https://reviews.apache.org/r/4629/#comment14791>
Why we need a converter?
src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
<https://reviews.apache.org/r/4629/#comment14792>
Whats the NULL_CONTROLLER about?
src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
<https://reviews.apache.org/r/4629/#comment14793>
So we don't close scanners anymore?
src/main/java/org/apache/hadoop/hbase/client/HConnection.java
<https://reviews.apache.org/r/4629/#comment14794>
Why do we need to pollute HConnection w/ higher level notions such as
RegionClientProtocol (or ClientProtocol?).... hmmm ClientProtocol would be ok
but not RegionClientProtocol...
src/main/java/org/apache/hadoop/hbase/client/HConnection.java
<https://reviews.apache.org/r/4629/#comment14795>
I wonder if this needs to be public and in the Interface? Could it be an
internal thing? How uses this thing that comes out? Maybe it needs to be here
but sure seems like an internal thing: i.e. we pass hostname and port of a
particular regionserver but then internally as we go about the cluster the
client will go to new regionservers and set up connections....
Looking around though, it seems that while most uses of this method should
be shut down: e.g. over in catalog package and replaced by calls that go via
HTable, there are a few places we need this still probably .. as in the master
sendRegionClose, etc. calls. So you can't get rid of it.
But this looks like it should be called RegionServerProtocol
or ClientProtocol and not RegionClientProtocol. It connects to a
RegionServer not a Region.....
Or what you think Jimmy? When I look at the RegionClient proto file, is
it true to say that in each message, we MUST pass a region since we are going
against a particular region... which would mean this is indeed a
RegionClientProtocol (you just have to specify coordinates in two steps; 1.
pass servername setting up connection, then 2. for any call on the connection,
need to specify the region.....)
src/main/java/org/apache/hadoop/hbase/client/HConnectionManager.java
<https://reviews.apache.org/r/4629/#comment14796>
Move these defines into this class rather than up in HConstants?
src/main/java/org/apache/hadoop/hbase/client/HConnectionManager.java
<https://reviews.apache.org/r/4629/#comment14797>
Whats happening here? We want to drop the methods that took hostname and
port only and move to those that take servername?
src/main/java/org/apache/hadoop/hbase/client/HConnectionManager.java
<https://reviews.apache.org/r/4629/#comment14798>
Is this good? Should we have servername? What if server restarts in
between? Would we want to notice that we don't have a connection to new
instantiation and go create one?
src/main/java/org/apache/hadoop/hbase/client/HConnectionManager.java
<https://reviews.apache.org/r/4629/#comment14799>
Does this need to be synchronized at all?
src/main/java/org/apache/hadoop/hbase/client/ScannerCallable.java
<https://reviews.apache.org/r/4629/#comment14800>
I suppose HBaseClient down in rpc knows it because it has to deserialize
the pb?
src/main/java/org/apache/hadoop/hbase/client/ScannerCallable.java
<https://reviews.apache.org/r/4629/#comment14801>
scannerid is internal or something now?
src/main/java/org/apache/hadoop/hbase/client/ServerCallable.java
<https://reviews.apache.org/r/4629/#comment14802>
Not your fault but server is a bad variable name for what this is, huh..
src/main/java/org/apache/hadoop/hbase/io/HbaseObjectWritable.java
<https://reviews.apache.org/r/4629/#comment14803>
Do you have to? This stuff is nasty enough w/o lettting it out of this
package.
src/main/java/org/apache/hadoop/hbase/ipc/RegionProtocols.java
<https://reviews.apache.org/r/4629/#comment14804>
Fix
src/main/java/org/apache/hadoop/hbase/ipc/RegionProtocols.java
<https://reviews.apache.org/r/4629/#comment14805>
What is this for?
src/main/java/org/apache/hadoop/hbase/ipc/WritableRpcEngine.java
<https://reviews.apache.org/r/4629/#comment14806>
Is ServiceException a pb exception?
src/main/java/org/apache/hadoop/hbase/protobuf/ProtobufUtil.java
<https://reviews.apache.org/r/4629/#comment14807>
Why not throw ServiceException?
src/main/java/org/apache/hadoop/hbase/protobuf/ProtobufUtil.java
<https://reviews.apache.org/r/4629/#comment14808>
Ugh. KeyValue needs to be an Interface that both pb and our current KV
implements.
This will be a performance killer? Should Result let out the raw pb KV?
src/main/java/org/apache/hadoop/hbase/protobuf/ProtobufUtil.java
<https://reviews.apache.org/r/4629/#comment14809>
Good one. I should use this in stuff I committed recently
src/main/java/org/apache/hadoop/hbase/protobuf/ProtobufUtil.java
<https://reviews.apache.org/r/4629/#comment14810>
Its as though we should give clients a way to pass in the raw pbs rather
than have them go via our versions of Get, Delete, etc.
src/main/java/org/apache/hadoop/hbase/protobuf/ProtobufUtil.java
<https://reviews.apache.org/r/4629/#comment14811>
white space
src/main/java/org/apache/hadoop/hbase/protobuf/RegionAdminProtocol.java
<https://reviews.apache.org/r/4629/#comment14812>
Is this just regionadmin protocol? Or is it general admin?
src/main/java/org/apache/hadoop/hbase/protobuf/RegionClientProtocol.java
<https://reviews.apache.org/r/4629/#comment14813>
This is probably a good idea.

bq. Summary
bq. -------
bq.
bq. This is the client protocol part of region interface. The admin protocol
part will be done in a different jira.
bq.
bq. The HRegionInterface is still there since the admin part is not done yet.
The other reason is that in case some people still wants the old interface
bq.
bq. Filters, comparators and coprocessor parameters are still Writable. They
will be addressed in different jiras.
bq.
bq. The existing client interface is not changed so that we don't break
existing clients.

bq. This addresses bug HBASE-5620.
