bq. Yes, this matches up with server side. If not using kerberos auth,
then does SIMPLE auth, otherwise if a token is present does DIGEST, otherwise
requires kerberos ticket.

I'd say if copied from hadoop, don't clean it up. Just leave it.

bq.
bq. Gary Helmling wrote:
bq. Yeah, doesn't do "length" currently. I could add it, but asynchbase
would still have to deal with the sasl negotiation on connection setup.
asynchbase is not going to be doing secure rpc anytime soon if ever so don't
worry about it.

bq. TRACELOG comes from HBaseServer I think. We added it with the simple
rpc call introspection I did. We wanted it to be a separate logger so it could
be easily enabled to get those stats without bringing in all the rest of the
debug logging.
ok

problem).
Don't bother fixing the hadoop copies (you'll be working on it till cows come
home and then next update will mess it all up again -- not to mention the pain
mapping hadoop to the cleaned up hbase version)

bq. Gary Helmling wrote:
bq. It's currently instantiated from SecureServer, so we need to access it
somehow. With secured ZK access, znode ACLs will prevent creating a secret
manager instance to obtain the secret keys. There is an opening here with
coprocessors though, since they run in process on the RS. We'll ultimately
need to lock those down separately.
Make a comment for now?

bq. Summary
bq. -------
bq.
bq. This patch creates a new secure RPC engine for HBase, which provides
Kerberos based authentication of clients, and a token-based authentication
mechanism for mapreduce jobs. Primary components of the patch are:
bq.
bq. - a new maven profile for secure Hadoop/HBase: hadoop-0.20S
bq. - Secure Hadoop dependent classes are separated under a pseudo-module in
the security/ directory. These source and test directories are only including
if building the secure Hadoop profile
bq. - Currently the security classes get packaged with the regular HBase
build artifacts. We need a way to at least override project.version, so we can
append something like a "-security" suffix indicating the additional security
components.
bq. - The pseudo-module here is really a half-step forward. It enables the
security code to be optionally included in the build for now, and sets up the
structure for a security module. But we still will want to pursue full
modularization (see HBASE-4336), which will allow packing the security code in
a separate build artifact.
bq.
bq. - a new RPC engine providing kerberos and token-based authentication:
org.apache.hadoop.hbase.ipc.SecureRpcEngine
bq. - implementation under
security/src/main/java/org/apache/hadoop/hbase/ipc/
bq. - The implementation classes extend the existing HBaseClient and
HBaseServer to share as much of the RPC code as possible. The main override is
of the connection classes to allow control over the SASL negotiation of secure
connections
bq.
bq. - existing RPC changes
bq. - The existing HBaseClient and HBaseServer have been modified to make
subclassing possible
bq. - All references to Hadoop UserGroupInformation have been replaced with
org.apache.hadoop.hbase.security.User to insulate from future dependencies on
specific Hadoop versions
bq.
bq. - a coprocessor endpoint for obtaining new authentication tokens:
TokenProvider, and supporting classes for token generation and synchronization
(incorporating HBASE-3615)
bq. - implementation is under
security/src/main/java/org/apache/hadoop/hbase/security/token/
bq. - Secret keys for token generation and verification are synchronized
throughout the cluster in zookeeper, under /hbase/tokenauth/keys
bq.
bq.
bq. To enable secure RPC, add the following configuration to hbase-site.xml:
bq.
bq. <property>
bq. <name>hadoop.security.authorization</name>
bq. <value>true</value>
bq. </property>
bq. <property>
bq. <name>hadoop.security.authentication</name>
bq. <value>kerberos</value>
bq. </property>
bq. <property>
bq. <name>hbase.rpc.engine</name>
bq. <value>org.apache.hadoop.hbase.ipc.SecureRpcEngine</value>
bq. </property>
bq. <property>
bq. <name>hbase.coprocessor.region.classes</name>
bq. <value>org.apache.hadoop.hbase.security.token.TokenProvider</value>
bq. </property>
bq.
bq. In addition, the master and regionserver processes must be configured for
kerberos authentication using the properties:
bq.
bq. * hbase.(master|regionserver).keytab.file
bq. * hbase.(master|regionserver).kerberos.principal
bq. * hbase.(master|regionserver).kerberos.https.principal
bq.
bq.
bq. This addresses bug HBASE-2742.

> Provide strong authentication with a secure RPC engine
> ------------------------------------------------------
>
> Key: HBASE-2742
> URL: https://issues.apache.org/jira/browse/HBASE-2742
> Project: HBase
> Issue Type: Improvement
> Components: ipc
> Reporter: Gary Helmling
> Priority: Critical
> Fix For: 0.92.0
>
>
> The HBase RPC code (org.apache.hadoop.hbase.ipc.*) was originally forked off
> of Hadoop RPC classes, with some performance tweaks added. Those
> optimizations have come at a cost in keeping up with Hadoop RPC changes
> however, both bug fixes and improvements/new features.
> In particular, this impacts how we implement security features in HBase (see
> HBASE-1697 and HBASE-2016). The secure Hadoop implementation (HADOOP-4487)
> relies heavily on RPC changes to support client authentication via kerberos
> and securing and mutual authentication of client/server connections via SASL.
> Making use of the built-in Hadoop RPC classes will gain us these pieces for
> free in a secure HBase.
> So, I'm proposing that we drop the HBase forked version of RPC and convert to
> direct use of Hadoop RPC, while working to contribute important fixes back
> upstream to Hadoop core. Based on a review of the HBase RPC changes, the key
> divergences seem to be:
> HBaseClient:
> - added use of TCP keepalive (HBASE-1754)
> - made connection retries and sleep configurable (HBASE-1815)
> - prevent NPE if socket == null due to creation failure (HBASE-2443)
> HBaseRPC:
> - mapping of method names <-> codes (removed in HBASE-2219)
> HBaseServer:
> - use of TCP keep alives (HBASE-1754)
> - OOME in server does not trigger abort (HBASE-1198)
> HbaseObjectWritable:
> - allows List<> serialization
> - includes it's own class <-> code mapping (HBASE-328)
> Proposed process is:
> 1. open issues with patches on Hadoop core for important fixes/adjustments
> from HBase RPC (HBASE-1198, HBASE-1815, HBASE-1754, HBASE-2443, plus a
> pluggable ObjectWritable implementation in RPC.Invocation to allow use of
> HbaseObjectWritable).
> 2. ship a Hadoop version with RPC patches applied -- ideally we should avoid
> another copy-n-paste code fork, subject to ability to isolate changes from
> impacting Hadoop internal RPC wire formats
> 3. if all Hadoop core patches are applied we can drop back to a plain vanilla
> Hadoop version
> I realize there are many different opinions on how to proceed with HBase RPC,
> so I'm hoping this issue will kick off a discussion on what the best approach
> might be. My own motivation is maximizing re-use of the authentication and
> connection security work that's already gone into Hadoop core. I'll put
> together a set of patches around #1 and #2, but obviously we need some
> consensus around this to move forward. If I'm missing other differences
> between HBase and Hadoop RPC, please list as well. Discuss!
