Subject [jira] [Created] (MAPREDUCE-4101) nodemanager depends on /bin/bash
Date Tue, 03 Apr 2012 18:00:29 GMT
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
