system-metrics | System Metrics is a Rails 3 Engine | Analytics library

I have two services deployed on Google cloud infrastructure; Service 1 runs on Compute Engine and Service 2 on Cloud Run and I'd like to log their memory usage via the ekg-core library (https://hackage.haskell.org/package/ekg-core-0.1.1.7/docs/System-Metrics.html).

The logging bracket is similar to this :

I am trying to export a hive table to mysql database whose data is tab delimited as stored in HDFS but the job is failing every time after mapper phase.

I have referred to many link and resources and cross checked my export command like export-directory, table name and other factors. Also the schema of both the tables are same but still didn't have any idea why the jobs are failing every time.

Schema in hive :

I'm basically trying to run my first Hadoop MapReduce routine, and I have to use Hadoop and MapReduce, as I am doing this for a class project. I want to use Python for the mapper and reducer as I am most comfortable with this language and it is most familiar to my peers. I felt like the easiest way for me to set this up was through a Google DataProc instance, so I have that running as well. I'll describe what I have done and what resources I have used, but I am relatively new to this and I might be missing something.

Dataproc Configuration

Dataproc 1

Dataproc 2

Dataproc 3

And, then, I'm able to SSH into my primary node. I have the mapper.py and reducer.py files stored in a Google Cloud Storage bucket.

Mapper and reducer code is from this Micheal Noll blog post, modified to work with Python 3.

mapper.py:

I'm trying to gather max and min temperature of a particular station and then finding the sum of temperature per different day but i keep getting an error in the mapper and Have tried a lot of other ways such as use stringtokenizer but same thing, i get an error.

Sample Input.

Station Date(YYYYMMDD) element temperature flag1 flat2 othervalue

i only need station, date(key), element and temperature from the input

I am trying to use Flinks monitoring REST API in order to retrieve some metrics for a specific time period.

Looking at the documentation, I can find the metrics of the job by navigating to http://hostname:8081/jobs/:jobid and I have the following:

I install Hadoop 2.9.0 and I have 4 nodes. The namenode and resourcemanager services are running on master and datanodes and nodemanagers are running on slaves. Now I wanna run a python MapReduce job. But Job not successful! Please tell me what should I do?

Log of running of job in terminal:

I have 3 nodes , one namenode1, datanode1 and datanode2. Scoop and mysql are installed on namenode1.

when can c the list of database as test.

I use hadoop3.1.0 to run Mapreduce WordCount program on Ubuntu,but it always got this INFO.

I saw someone ask this similar question before,but that can't work.

I want to know which file should i modify,or something that i miss.

My java program is from here.

master@kevin-VirtualBox:~/MapReduceTutorial$ $HADOOP_HOME/bin/hadoop jar ProductSalePerCountry.jar /inputMapReduce /mapreduce_output_sales

I'm new to Mahout and Random-Forest.I wanna classify my dataset and have built the random-forest on my three virtual Hadoop nodes. As we know,first of all,I made the descriptor(/des.info).And I built the classifier(/user/hadoop/forest) .There was an error but it completed successfully.However I was stuck when I tried to test it. My systems are all CentOS7 with hadoop-3.0.0.

Here is the HDFS:
