Subject [jira] [Commented] (HADOOP-8767) secondary namenode on slave machines

Arpit Gupta commented on HADOOP-8767:
-------------------------------------

@Giovanni

I checked trunk and it looks like the same problem exists in trunk where we source the hadoop-env.sh
after reading the command line arguments. So the same fixes should apply there as well. Could
you generate a patch for trunk also.


For hadoop 1.0.3 we need to create the patch for branch-1 and that will be ported to branch-1.1
and branch-1.0 so the future 1.x releases can pick up the fix.

> when the default value for HADOOP_SLAVES is changed in hadoop-env.sh the hdfs starting
(with start-dfs.sh) creates secondary namenodes on all the machines in the file conf/slaves
instead of conf/masters.
