Description

We've got 3 of them on trunk.

[INFO] org.apache.hbase:hbase-server:jar:0.95-SNAPSHOT
[INFO] +- io.netty:netty:jar:3.5.0.Final:compile
[INFO] +- org.apache.zookeeper:zookeeper:jar:3.4.3:compile
[INFO] | - org.jboss.netty:netty:jar:3.2.2.Final:compile

[INFO] org.apache.hbase:hbase-hadoop2-compat:jar:0.95-SNAPSHOT
[INFO] +- org.apache.hadoop:hadoop-client:jar:2.0.2-alpha:compile
[INFO] | +- org.apache.hadoop:hadoop-mapreduce-client-app:jar:2.0.2-alpha:compile
[INFO] | | - org.jboss.netty:netty:jar:3.2.4.Final:compile

The patch attached:

• fixes this for hadoop 1 profile
• bump the netty version to 3.5.9
• does not fix it for hadoop 2. I don't know why, but I haven't investigate: as it's still alpha may be they will change the version on hadoop side anyway.

Tests are ok.

I haven't really investigated the differences between netty 3.2 and 3.5. A quick search seems to say it's ok, but don't hesitate to raise a warning...
