(Updated Oct. 7, 2016, 7:18 a.m.) Review request for oozie, András Piros, Peter Cseh, Peter Bacsko, and Robert Kanter. Changes ------- Fixes according to review comments: - rename oozie.ssl to oozie.https, - added ShutdownHook to stop oozie services. Repository: oozie-git Description ------- Embedding jetty into Oozie so that it can run as a standalone application. The changes also try to address OOZIE-2317 (i.e. Tomcat 6 is EOL). New functionality - New module (server) is added that sets up an embedded Jetty server and start Oozie services. Servlet mapping is done by reading web.xml of webapp at runtime. JSP is handled with custom code. Server version is not revealed in server repsonses. - SSL protocols and ciphers can be configured via system properties and environment variables. Precedence: system properties, environment variables, default values Changes in existing code - Excluded jetty 6 dependencies from core and updated tests accordingly Packaging - oozie.sh is modified so that it starts Oozie with embedded jetty by default. If someone would like to use tomcat for any reason, they can set an environment variable (e.g. OOZIE_USE_TOMCAT=1). TODO: - Add more tests - Add more documentation - Code cleanup + refactoring in packaging and core parts - Maven clean up - Allow to tune more Jetty settings (for example threadpool) - More security measures (e.g. protect against clickjacking, CSRF, etc.) - Update Oozie Documentation Diffs (updated) ----- core/src/main/java/org/apache/oozie/util/Instrumentation.java fa1e92a0f1fadfb66c5e66fea5f26f57579080e7 core/src/main/resources/oozie-default.xml e71ebe3b7a85e6b23176ef30713af63847144498 distro/pom.xml c50572c57a376b28963d4e7da8ac7df777fe0480 distro/src/main/bin/oozie-jetty-server.sh PRE-CREATION distro/src/main/bin/oozie-setup.sh 79b049bccceb2690f8a673a885a615c8d4d9578c distro/src/main/bin/oozie-sys.sh 97d55a2b69c34ede007d4f65cdfc66f1ac2cfd13 distro/src/main/bin/oozied.sh a869c3da177c863a068f2af45c7bca9d5cb771ac pom.xml 704a2eeee9f4e4805e3e08c2a547b2a375f6b1b2 server/pom.xml PRE-CREATION server/src/main/assemblies/empty.xml PRE-CREATION server/src/main/java/org/apache/oozie/server/EmbeddedOozieServer.java PRE-CREATION server/src/main/java/org/apache/oozie/server/JspHandler.java PRE-CREATION server/src/main/java/org/apache/oozie/server/SSLServerConnectorFactory.java PRE-CREATION server/src/main/resources/checkstyle-header.txt PRE-CREATION server/src/main/resources/checkstyle.xml PRE-CREATION server/src/test/java/org/apache/oozie/server/TestEmbeddedOozieServer.java PRE-CREATION server/src/test/java/org/apache/oozie/server/TestSSLServerConnectorFactory.java PRE-CREATION src/main/assemblies/distro.xml 1ffbfd6d2ba33b390999e9094cbb336fbce45c21 Diff: https://reviews.apache.org/r/52399/diff/ Testing ------- - Tested basic functionality by executing a workflow that uses the sample JavaAction - without SSL - on a 2.4.0 pseudo Hadoop cluster - SSL with Kerberos is using a test CDH cluster - Added new unit tests that check - If oozie.ssl.enabled is not specified, server starts without SSL settings - If oozie.ssl.enabled is specified, server starts with SSL settings - SSL protocols and ciphers can be configured via system properties and environment variables - Ran subset of tests using Hadoop-2 profile - mvn clean package assembly:single -DjavaVersion=1.8 -DtargetVersion=1.7 -Dtest=TestJavaActionExecutor -Phadoop-2 -Dhadoop.version=2.4.0 Thanks, Attila Sasvari
