0.18.1 breaks SOCKS server setting
----------------------------------
Key: HADOOP-4484
URL: https://issues.apache.org/jira/browse/HADOOP-4484
Project: Hadoop Core
Issue Type: Sub-task
Affects Versions: 0.18.1
Reporter: Eugene Hung
Priority: Minor
Our cluster is behind a gateway, and we asked users to use hadoop.socks.server
to access the cluster.
Recently, we "upgraded" our cluster from 0.17.2 to 0.18.1. However, this
creates the following problem:
Wrote input for Map #4
Starting Job
java.net.UnknownHostException: unknown host: hadoop-master
at org.apache.hadoop.ipc.Client$Connection.<init>(Client.java:195)
at org.apache.hadoop.ipc.Client.getConnection(Client.java:779)
at org.apache.hadoop.ipc.Client.call(Client.java:704)
at org.apache.hadoop.ipc.RPC$Invoker.invoke(RPC.java:216)
at org.apache.hadoop.dfs.$Proxy0.getProtocolVersion(Unknown Source)
at org.apache.hadoop.ipc.RPC.getProxy(RPC.java:319)
Nothing else has changed and we were able to duplicate this error on a separate
cluster setup, so we
believe 0.18.1 has broken this feature.
