various issues with running yarn proxyserver --------------------------------------------
Key: MAPREDUCE-3916 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3916 Project: Hadoop Map/Reduce Issue Type: Bug Components: mrv2, resourcemanager, webapps Affects Versions: 0.23.1 Reporter: Roman Shaposhnik Seem like yarn proxyserver is not operational when running out of the 0.23.1 RC2 tarball. # Setting yarn.web-proxy.address to match yarn.resourcemanager.address doesn't disable the proxyserver (althought not setting yarn.web-proxy.address at all correctly disable it and produces a message: org.apache.hadoop.yarn.YarnException: yarn.web-proxy.address is not set so the proxy will not run). This contradicts the documentation provided for yarn.web-proxy.address in yarn-default.xml # Setting yarn.web-proxy.address and running the service results in the following: {noformat} $ ./sbin/yarn-daemon.sh start proxyserver starting proxyserver, logging to /tmp/hadoop-0.23.1/logs/yarn-rvs-proxyserver-ahmed-laptop.out /usr/java/64/jdk1.6.0_22/bin/java -Dproc_proxyserver -Xmx1000m -Dhadoop.log.dir=/tmp/hadoop-0.23.1/logs -Dyarn.log.dir=/tmp/hadoop-0.23.1/logs -Dhadoop.log.file=yarn-rvs-proxyserver-ahmed-laptop.log -Dyarn.log.file=yarn-rvs-proxyserver-ahmed-laptop.log -Dyarn.home.dir= -Dyarn.id.str=rvs -Dhadoop.root.logger=INFO,DRFA -Dyarn.root.logger=INFO,DRFA -Djava.library.path=/tmp/hadoop-0.23.1/lib/native -Dyarn.policy.file=hadoop-policy.xml -Dhadoop.log.dir=/tmp/hadoop-0.23.1/logs -Dyarn.log.dir=/tmp/hadoop-0.23.1/logs -Dhadoop.log.file=yarn-rvs-proxyserver-ahmed-laptop.log -Dyarn.log.file=yarn-rvs-proxyserver-ahmed-laptop.log -Dyarn.home.dir=/tmp/hadoop-0.23.1 -Dhadoop.root.logger=INFO,DRFA -Dyarn.root.logger=INFO,DRFA -Djava.library.path=/tmp/hadoop-0.23.1/lib/native -classpath /tmp/hadoop-0.23.1/etc/hadoop:/tmp/hadoop-0.23.1/etc/hadoop:/tmp/hadoop-0.23.1/etc/hadoop:/tmp/hadoop-0.23.1/share/hadoop/common/lib/*:/tmp/hadoop-0.23.1/share/hadoop/common/*:/tmp/hadoop-0.23.1/share/hadoop/hdfs:/tmp/hadoop-0.23.1/share/hadoop/hdfs/lib/*:/tmp/hadoop-0.23.1/share/hadoop/hdfs/*:/tmp/hadoop-0.23.1/share/hadoop/mapreduce/lib/*:/tmp/hadoop-0.23.1/share/hadoop/mapreduce/*:/tmp/hadoop-0.23.1/share/hadoop/mapreduce/*:/tmp/hadoop-0.23.1/share/hadoop/mapreduce/lib/* org.apache.hadoop.yarn.server.webproxy.WebAppProxyServer {noformat} with the following message found in the logs: {noformat} 2012-02-24 09:26:31,099 FATAL org.apache.hadoop.yarn.server.webproxy.WebAppProxy: Could not start proxy web server java.io.FileNotFoundException: webapps/proxy not found in CLASSPATH at org.apache.hadoop.http.HttpServer.getWebAppsPath(HttpServer.java:532) at org.apache.hadoop.http.HttpServer.<init>(HttpServer.java:224) at org.apache.hadoop.http.HttpServer.<init>(HttpServer.java:164) at org.apache.hadoop.yarn.server.webproxy.WebAppProxy.start(WebAppProxy.java:85) at org.apache.hadoop.yarn.service.CompositeService.start(CompositeService.java:68) at org.apache.hadoop.yarn.server.webproxy.WebAppProxyServer.main(WebAppProxyServer.java:76) {noformat} -- This message is automatically generated by JIRA.
