DarinJ commented on MYRIAD-176: ------------------------------- This isn't really a bug, it's an artifact of the fact we echo the command before actually running it. It might be we can remove the echo at this point, or replace $ with \$ in the echo line. > YARN_HOME value ignored in " $YARN_HOME/bin/yarn nodemanager" > ------------------------------------------------------------- > > Key: MYRIAD-176 > URL: https://issues.apache.org/jira/browse/MYRIAD-176 > Project: Myriad > Issue Type: Bug > Components: Scheduler > Reporter: Zhongyue Luo > > Below is the stdout log from one of my node managers. > sudo tar -zxpf hadoop-2.5.0-cdh5.3.1.tar.gz && sudo chown yarn . && cp conf > hadoop-2.5.0-cdh5.3.1/etc/hadoop/yarn-site.xml; export > YARN_HOME=hadoop-2.5.0-cdh5.3.1; sudo -E -u yarn -H env > JAVA_HOME=/usr/java/default YARN_HOME=hadoop-2.5.0-cdh5.3.1 > YARN_NODEMANAGER_OPTS=-Dyarn.nodemanager.container-executor.class=org.apache.hadoop.yarn.server.nodemanager.DefaultContainerExecutor > -Dnodemanager.resource.cpu-vcores=4 -Dnodemanager.resource.memory-mb=4096 > -Dmyriad.yarn.nodemanager.address=0.0.0.0:31873 > -Dmyriad.yarn.nodemanager.localizer.address=0.0.0.0:31142 > -Dmyriad.yarn.nodemanager.webapp.address=0.0.0.0:31765 > -Dmyriad.mapreduce.shuffle.port=31515 /bin/yarn nodemanager > at the end of the line, you can see that it is "31515 /bin/yarn nodemanager" > where there are two spaces between '31515' and '/bin'. > This seems to happen due to the java code not recognizing the $YARN_HOME > value in > https://github.com/apache/incubator-myriad/blob/master/myriad-scheduler/src/main/java/org/apache/myriad/scheduler/NMExecutorCLGenImpl.java#L65 > causing an additional blank space in front of '/bin'. However all > nodemanagers seem to run just fine despite the attempt to execute yarn on > /bin. I've tested this with vanilla hadoop 2.5.0 and 2.7.0 and CDH 5.3.1 all > cases showing same symptoms. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
