Using CDH 5, when I run my oozie workflow I no longer see log-statements from my mappers (log4j, slf4j). I even tried System.out.println - I still don't see the statements. Is there a setting I'm missing?
It turned out that the logs are still there except you need to manually point your browser to it. For example, clicking on a map-reduce action still opens the job log page something like (http://localhost:50030/jobdetails.jsp?jobid=job_201510061631_2112).
However to get the result for the actual job, I need to increment the jobid to job_201510061631_2113

log is showing like command took 49.03 minutes ,i can see status of job as "succeeded" but data is not loaded.
Kindly help me out with possible assumptions.
In the log file, please check for the number of records processed and loaded in each step. Have a look in the tables used in the join.
Perform more detailed analysis by, executing the steps manually and analyse the outcome.
Thanks.
may be i'm just missing smth, but i just have no more ideas where to look.
i read messages from 2 sources, make a join based on a common key and sink
it all to kafka.
val env = StreamExecutionEnvironment.getExecutionEnvironment
env.setParallelism(3)
...
source1
.keyBy(_.searchId)
.connect(source2.keyBy(_.searchId))
.process(new SearchResultsJoinFunction)
.addSink(KafkaSink.sink)
so it perfectly works when i launch it locally and it also works on cluster with Parallelism set to 1, but with 3 not any more.
When i deploy it to 1 job manager and 3 taskmanagers and get every Task in "RUNNING" state, after 2
minutes (when nothing is comming to sink) one of the taskmanagers gets the following log:
https://gist.github.com/zavalit/1b1bf6621bed2a3848a05c1ef84c689c#file-gistfile1-txt-L108
and the whole thing just shuts down.
i'll appreciate any hint.
tnx, in an advance.
The problem appears to be that this task manager -- flink-taskmanager-12-2qvcd (10.81.53.209) -- is unable to talk to at least one of the other task managers, namely flink-taskmanager-12-57jzd (10.81.40.124:46240). This is why the job never really starts to run.
I would check in the logs for this other task manager to see what it says, and I would also review your network configuration. Perhaps a firewall is getting in the way?
I am thinking to integrate console outputting technology of jenkins job in one my application. We see that jenkins jobs continuously prints the command output in console with minimum buffer and no page refresh. Can anyone detail how its achieved in jenkins?
Basically it has an ajax request which asks for chunks of log every second. More info can be found here. Links to files mentioned in the post; LargeText, console.jelly, progressiveTest.jelly.
I have created a dbms scheduler job which should write a short string to the alert log of each instance of the 9 databases on our 2-node 11g Oracle RAC cluster, once every 24 hours.
The job action is:
'dbms_system.ksdwrt(2, to_char(sysdate+1,''rrrr-mm-dd'') || ''_First'');'
which should write a line like:
2014-08-27_First
The job runs succesfully according to its log, and it does write what it's supposed to, but not always. It's only been scheduled for a few days, so I can't be certain, but it looks as if it will only write to one instance's alert log. Logs on both sides seem to be getting written to, but if it's on one side it's not on the other, so it appears. There is however no indication whatever of any failure in the job itself.
Can anyone shed any light on this behaviour? Thanks.
I'm currently developing a set of map reduce tasks that have to be run in a particular order. I'm looking to use Oozie to manage the dependencies and running of this workflow. There's one key feature that I need, though, and I can't find any documentation that suggests that it is possible.
Basically, I am looking for a way to setup an action that checks to see if its output file is newer than the input file (and associated map-reduce code) has changed before executing the action. If so, it would skip executing the action. This way, I could make a change to a script and have only that stage of the workflow (and any that depend on its output) run.
Does anyone know how I'd go about doing this?
How about using shell action in oozie where in you can run a shell script which actually checks for difference in the content of the defined file. And then on success of this action goto the map-red action and continue your job else goto fail case and kill your job.
Hope this idea helps you , If this is what you are looking for
