Running start-all.sh it logs the above message (only for tasktracker),
i figured out it was essentially the following command, then also
tried to pick up a specific config.
Full message at the bottom
hadoop --config ../conf tasktracker
// start-all.sh uses this command What conf files does it
use when the dir is specified?
hadoop --config ../conf/hadoop-localhost.xml tasktracker
// same thing, see mapred.job.tracker setting below
hadoop tasktracker
// same thing
I tried to debug this also, but am not figuring out where
mapred.job.tracker=local is set, it is in None of my config files.
some type of default that my xml file isn't overriding?
hadoop-localhost.xml has:
<property>
<name>mapred.job.tracker</name>
<value>localhost:54311</value>
<description>The host and port that the MapReduce job tracker runs
at. If "local", then jobs are run in-process as a single map
and reduce task.
</description>
</property>
