"The Dataflow appears to be stuck" -


i running dataflow last ran few months ago. same client, same dataflow version (0.7.0dev0). unfortunately fails in mysterious ways did not before.

i starting job, , first stage is:

(8733429d016bc2fb): executing operation read datastore/split query+read datastore/groupbykey/reify+read datastore/groupbykey/write

but itgives following error after 1 hour:

(e88cb3c076926976): workflow failed. causes: (e88cb3c07692626f): dataflow appears stuck. please reach out dataflow team @ http://stackoverflow.com/questions/tagged/google-cloud-dataflow.

i'm not sure how debug or investigate further. worked few months ago same code, doesn't work (with 4-5x larger dataset, of 200-300k records, nothing crazy...)

this fixed upgrading 2.0.0 (thanks ben chambers!) seems 0.7.0 no longer worked cloud dataflow.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
