[ http://issues.apache.org/jira/browse/HADOOP-36?page=all ] Doug Cutting closed HADOOP-36: ------------------------------
> Adding some uniformity/convenience to environment management > ------------------------------------------------------------ > > Key: HADOOP-36 > URL: http://issues.apache.org/jira/browse/HADOOP-36 > Project: Hadoop > Type: Improvement > Components: conf > Reporter: Bryan Pendleton > Fix For: 0.1.0 > > Currently, "slaves" are loaded from ~/.slaves. What would be better would be > to default from something like conf/hadoop-slaves > Perhaps split slaves, having a different set for "datanodes" vs. > "tasktracker" nodes. ie, conf/hadoop-slaves-tasktracker, > conf/hadoop-slaves-datanodes, or some similar split. There's the possibility > it's worth building in the assumption that tasktracker is a superset, and > thus implicitly includes datanodes, but this might be a bad assumption. > Also, make sure all scripts source something like conf/hadoop-env.sh. Thus, > the user can edit hadoop-env.sh to specify JAVA_HOME, or an alternate > HADOOP_SLAVES location. It would also be desirable to have a seed CLASSPATH > here. Possibly name it HADOOP_CLASSPATH, to make it explicit and not make > hadoop scripts possibly interact with an otherwise-set system CLASSPATH > variable. > These changes would probably be useful to the nutch project, too. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
