Hello everyone, I got two universal recommendation engine using the same events. And this morning I find the server busy running with 100% CPU, so I shut it down, tried to run up all the server. However, after `pio-start-all` succeeded, I ran `pio train` on the two engines, one succeeded with another failed. It returns the following error message:
*Exception in thread "main" org.apache.spark.SparkException: Job aborted due to stage failure: Task 1 in stage 47.0 failed 1 times, most recent failure: Lost task 1.0 in stage 47.0 (TID 156, localhost): org.apache.spark.util.TaskCompletionListenerException: Found unrecoverable error [10.1.3.100:9200 <http://10.1.3.100:9200>] returned Bad Request(400) - [MapperParsingException[failed to parse [t]]; nested: ElasticsearchIllegalArgumentException[unknown property [obj]]; ]; Bailing out..* * at org.apache.spark.TaskContextImpl.markTaskCompleted(TaskContextImpl.scala:112)* * at org.apache.spark.scheduler.Task.run(Task.scala:102)* * at org.apache.spark.executor.Executor$TaskRunner.run(Executor.scala:227)* * at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142)* * at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)* * at java.lang.Thread.run(Thread.java:745)* Any advise on how to solve the weird situation? Thank you! Best regards, Amy
