From e25d4d0fcbf3f2441bf44c243497870cc4dc724a Mon Sep 17 00:00:00 2001 From: Narayanan Venkateswaran Date: Wed, 27 Jul 2022 08:51:44 +0530 Subject: [PATCH] HADOOP-15980. Securing Hadoop RPC using SSL The work done in this pull request implements SSL support for Hadoop RPC using the following steps, 1. Add SSL support to the RPC server a. Creates a RPC server implementation (Server.java) to use Netty b. Juxtaposes the Netty Implementation alongside the Native Java NIO APIs. c. Add SSL Handlers to the Netty Pipeline d. Parameterizes the RPC unit tests to run with and without SSL. e. Split the new classes into the constituent source files to reduce the clutter in Server.java. 2. Add Netty support to the RPC client a. Creates a RPC Client implementation (Client.java) to use Netty b. Juxtaposes the Netty Implementation alongside the Native Java NIO APIs. c. Add SSL Handlers to the Netty Pipeline d. Parameterizes the RPC unit tests to run with and without Netty. e. Split the new classes into the constituent source files to reduce the clutter in Client.java. 3. Add configuration to turn Netty on and off. --- .../hadoop-client-minicluster/pom.xml | 4 + .../dev-support/findbugsExcludeFile.xml | 2 +- hadoop-common-project/hadoop-common/pom.xml | 6 + .../hadoop/fs/CommonConfigurationKeys.java | 29 + .../apache/hadoop/ipc/CallQueueManager.java | 2 +- .../java/org/apache/hadoop/ipc/Client.java | 150 +- .../apache/hadoop/ipc/ProtobufRpcEngine2.java | 4 +- .../org/apache/hadoop/ipc/RpcException.java | 2 +- .../org/apache/hadoop/ipc/RpcWritable.java | 2 +- .../java/org/apache/hadoop/ipc/Server.java | 1841 +---------------- .../hadoop/ipc/netty/client/IpcStreams.java | 139 ++ .../ipc/netty/client/NettyIpcStreams.java | 337 +++ .../ipc/netty/client/NioIpcStreams.java | 42 + .../hadoop/ipc/netty/server/Binder.java | 111 + .../hadoop/ipc/netty/server/Connection.java | 1232 +++++++++++ .../hadoop/ipc/netty/server/Listener.java | 96 + .../ipc/netty/server/NettyConnection.java | 180 ++ .../ipc/netty/server/NettyListener.java | 168 ++ .../ipc/netty/server/NettyResponder.java | 89 + .../ipc/netty/server/NettyThreadFactory.java | 77 + .../ipc/netty/server/NioConnection.java | 79 + .../hadoop/ipc/netty/server/NioListener.java | 349 ++++ .../hadoop/ipc/netty/server/NioResponder.java | 317 +++ .../hadoop/ipc/netty/server/Responder.java | 68 + .../apache/hadoop/security/SaslRpcClient.java | 2 +- .../apache/hadoop/security/SaslRpcServer.java | 7 +- .../hadoop/security/ssl/SSLFactory.java | 2 +- .../apache/hadoop/ipc/RPCCallBenchmark.java | 28 +- .../org/apache/hadoop/ipc/TestAsyncIPC.java | 25 +- .../apache/hadoop/ipc/TestFairCallQueue.java | 23 +- .../java/org/apache/hadoop/ipc/TestIPC.java | 232 ++- .../hadoop/ipc/TestIPCServerResponder.java | 45 +- .../apache/hadoop/ipc/TestProtoBufRpc.java | 35 +- .../java/org/apache/hadoop/ipc/TestRPC.java | 164 +- .../hadoop/ipc/TestRPCCallBenchmark.java | 22 +- .../hadoop/ipc/TestRPCServerShutdown.java | 22 + .../hadoop/ipc/TestRPCWaitForProxy.java | 2 +- .../org/apache/hadoop/ipc/TestRpcBase.java | 8 +- .../hadoop/ipc/TestRpcServerHandoff.java | 8 +- .../org/apache/hadoop/ipc/TestSaslRPC.java | 76 +- .../org/apache/hadoop/ipc/TestServer.java | 36 +- .../hadoop/hdfs/TestDFSClientRetries.java | 84 +- .../impl/TestInterDatanodeProtocol.java | 16 +- 43 files changed, 4111 insertions(+), 2052 deletions(-) create mode 100644 hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/netty/client/IpcStreams.java create mode 100644 hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/netty/client/NettyIpcStreams.java create mode 100644 hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/netty/client/NioIpcStreams.java create mode 100644 hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/netty/server/Binder.java create mode 100644 hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/netty/server/Connection.java create mode 100644 hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/netty/server/Listener.java create mode 100644 hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/netty/server/NettyConnection.java create mode 100644 hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/netty/server/NettyListener.java create mode 100644 hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/netty/server/NettyResponder.java create mode 100644 hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/netty/server/NettyThreadFactory.java create mode 100644 hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/netty/server/NioConnection.java create mode 100644 hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/netty/server/NioListener.java create mode 100644 hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/netty/server/NioResponder.java create mode 100644 hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/netty/server/Responder.java diff --git a/hadoop-client-modules/hadoop-client-minicluster/pom.xml b/hadoop-client-modules/hadoop-client-minicluster/pom.xml index b8cb525669b1f..044a25df5f461 100644 --- a/hadoop-client-modules/hadoop-client-minicluster/pom.xml +++ b/hadoop-client-modules/hadoop-client-minicluster/pom.xml @@ -120,6 +120,10 @@ io.netty netty + + io.netty + netty-all + javax.servlet javax.servlet-api diff --git a/hadoop-common-project/hadoop-common/dev-support/findbugsExcludeFile.xml b/hadoop-common-project/hadoop-common/dev-support/findbugsExcludeFile.xml index 23e39d055ffc5..2c87cff89f64c 100644 --- a/hadoop-common-project/hadoop-common/dev-support/findbugsExcludeFile.xml +++ b/hadoop-common-project/hadoop-common/dev-support/findbugsExcludeFile.xml @@ -355,7 +355,7 @@ to process initial sasl response token included in the INITIATE --> -
