Yes, removed.

Yes, good catch.  Added.

What would you suggest?  An IOE here means there was a failure in deserializing 
the key as a Writable, which is bad, but need not be fatal.  Some 
authentication attempts based on the corrupted key may fail, but authentication 
using other existing keys may still be succeeding.  The only other option I can 
think of is aborting, but that could mean all RS's in the cluster going down, 
which is pretty bad in itself.

Any other options you can think of for how we handle this?

bq.  (Updated 2011-10-26 20:23:19)
bq.  
bq.  
bq.  Review request for hbase.
bq.  
bq.  
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.

bq.  -------
bq.  
bq.  A full test suite run showed failures in TestMasterFailover (timeout) and 
TestAvroServer.  I'll look into those.
bq.  
bq.  Cluster testing (1 master + 3 slaves in ec2) with Kerberos authentication 
and map reduce token authentication, using YCSB, RowCounter, 
PerformanceEvaluation.
