I have installed HDP 2.6.5 cluster using two machines.
I tryied to run the mapreduce example deployed with installation using following steps:
Log into HDFS user : su - hdfs
calling the wordcount jar file: hadoop jar /usr/hdp/220.127.116.110-37/hadoop-mapreduce/hadoop-mapreduce-examples.jar wordcount /user/dev_whorchani/testing.txt /user/dev_whorchani/output
The job can't run and i got the following message in yarn interface:
Log Aggregation Status
[Sat Feb 09 10:40:57 +0100 2019] Application is added to the scheduler and is not yet activated. Queue's AM resource limit exceeded. Details : AM Partition = <DEFAULT_PARTITION>; AM Resource Request = <memory:1024, vCores:1>; Queue Resource Limit for AM = <memory:5120, vCores:1>; User AM Resource Limit of the queue = <memory:5120, vCores:1>; Queue AM Resource Usage = <memory:5120, vCores:5>;
I tryied to increase the AM Queue in YARN, after change the node manager can't start so i roll-back the first setting of the scheduler.
