nodemanager depends on /bin/bash
--------------------------------
Key: MAPREDUCE-4101
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4101
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: nodemanager
Affects Versions: 0.23.1
Environment: FreeBSD 8.2 / 64 bit
Reporter: Radim Kolar
Currently nodemanager depends on bash shell. It should be well documented for
system not having bash installed by default such as FreeBSD. Because only basic
functionality of bash is used, probably changing bash to /bin/sh would work
enough.
i found 2 cases:
1. DefaultContainerExecutor.java creates file with /bin/bash hardcoded in
writeLocalWrapperScript. (this needs bash in /bin)
2. yarn-hduser-nodemanager-ponto.amerinoc.com.log:2012-04-03 19:50:10,798 INFO
org.apache.hadoop.yarn.server.nodemanager.DefaultContainerExecutor:
launchContainer: [bash, -c,
/tmp/nm-local-dir/usercache/hduser/appcache/application_1333474251533_0002/container_1333474251533_0002_01_000012/default_container_executor.sh]
this created script is also launched by bash - bash anywhere in path works - in
freebsd it is /usr/local/bin/bash
