Python subprocess with oozie

由 点点圈 提交于 2019-12-07 23:58:21
问题 I'm trying to use subprocess in a python script which I call within an oozie shell action. Subprocess is supposed to read a file which is stored in Hadoop's HDFS. I'm using hadoop-1.2.1 in pseudo-distributed mode and oozie-3.3.2. Here is the python script, named connected_subprocess.py : #!/usr/bin/python import subprocess import networkx as nx liste=subprocess.check_output("hadoop fs -cat /user/root/output-data/calcul-proba/final.txt",shell=True).split('\n') G=nx.DiGraph() f=open("/home/rlk

由 江枫思渺然 提交于 2019-12-07 08:21:46
问题 I want to run oozie coordinator with start time as sysdate. How do I do that? is it possible to put sysdate as start date ? Will it catch up? 回答1: You can make coorodinator's "start" refer to a variable - startTime, then overwrite its value with sysdate from command line, such as: oozie job -run -config ./coord.properties -DstartTime=`date -u "+%Y-%m-%dT%H:00Z"` adjust the time format if you are not using UTC time zone in your system. sample coordinator job xml: <coordinator-app name="my

You can capture output from shell script and pass it to java action.In the shell script , echo the property like 'dateVariable=${DATE}' and add the capture-output element int the shell action. This will let you capture dateVariable from shell script.In the java action, You can pass the captured variable as parameter as ${wf:actionData('shellAction')['dateVariable']} where shellAction is the shell action name.

问题 We have a Hadoop service in which we have multiple applications. We need to process the data for each of the applications by reexecuting the same workflow. These are scheduled to execute at the same time of the day. The issue is that when these jobs are running its hard to know for which application the job is running/failed/succeeded. Ofcourse, I can open the job coonfiguration and know it but that does take time since there are 10s of applications running under that service. Is there any
