Oops, you're using HDP 2.1 which means Hadoop 2.4, so property name is
mapreduce.tasktracker.map.tasks.maximum
and more importantly it should be irrelevant using Yarn for which map
slots don't matter. Explanation anyone ?

Hi
Adding an another TT may not be the only way, increasing
mapred.tasktracker.map.tasks.maximum could also do the trick
Explanation there :

Hi Rich,
Default setup, so presumably one. I opted to add a node rather
than change the number of task trackers and it now runs successfully.
Thank you!

How many tasktrackers do you have setup for your single node
cluster? Oozie runs each action as a java program on an
arbitrary cluster node, so running a workflow requires a
minimum of two tasktrackers.

Hi all,
I'm using oozie to run a hive script, but the map job is
not completing. The tracking page shows its progress as
100%, and there's no warnings or errors in the logs, it's
just sitting there with a state of 'RUNNING'.
As best I can make out from the logs, the last statement
in the hive script has been successfully parsed and it
tries to start the command, saying "launching job 1 of
3". That job is sitting there in the "ACCEPTED" state,
but doing nothing.
This is on a single-node cluster running Hortonworks Data
Platform 2.1. Can anyone suggest what might be the cause,
or where else to look for diagnostic information?
Thanks,
Charles
