[jira] [Updated] (BEAM-318) AvroCoder may be vulnerable to AVRO-607

Daniel Halperin updated BEAM-318:

Description: 
See AVRO-607

The hypothesis is that even though AvroCoder is threadsafe according to Avro's 
javadoc, an underlying bug in Avro library makes thread-unsafe access to a Java 
WeakHashMap. However I have not yet succeeded at reproducing the bug; with some 
failed attempts in the linked GitHub Pull Request history.

So, I've started digging into the {{FlinkBatchTransformTranslators}}. The only 
thing I've found: the items leave {{FlinkPartialReduceFunction}} groupped 
correctly (in respect to shard). Then they arrive to {{FlinkReduceFunction}} in 
groups but not all values of a given key at once.

I'm not sure how Flink shuffles/sorts the data. The direction you've looked: 
hashCode/comparator seems good, but I think the bug is outside the 
{{KvCoderComparator}}.

[jira] [Created] (BEAM-324) Improve TypeDescriptor inference of DoFn's created inside a generic PTransform

2016-06-02 Thread Ben Chambers (JIRA)
Ben Chambers created BEAM-324:
-

 Summary: Improve TypeDescriptor inference of DoFn's created inside 
a generic PTransform
 Key: BEAM-324
 URL: https://issues.apache.org/jira/browse/BEAM-324
 Project: Beam
  Issue Type: Bug
  Components: beam-model
Reporter: Ben Chambers
Assignee: Frances Perry
Priority: Minor


Commit 
https://github.com/apache/incubator-beam/commit/aa7f07fa5b22f3656d52dc9e1d4557bceb87c013
 introduced the ability to infer a {{TypeDescriptor}} from an object created 
inside a concrete instance of a {{PTransform}} and used it to simplify 
{{SimpleFunction}} usage.

We should probably look at using the same mechanism elsewhere, such as when 
inferring the output type of a {{ParDo}}.

One more finding: the reproduction of the bug depends on the total size of data 
not number of keys or elements per key. I've just modified the example by 
adding 5KB blob to each item and it fails with considerably smaller number of 
elements. May it be related to a mechanism used for keeping the data off the 
memory.

After taking a look at data it looks weird:
In a given shard there are sub-shards of data. Take a look at 
execution_split_sorted, the columns are: worker, key, number of values.

If you search, you will notice that a pairs of (worker, number of values) 
appear multiple times.

I'm adding a full log from an erroneous execution and analysis.

The analysis was to grep which key was processed on which shard. It seems that 
each key was processed on only one shard. I've re-run the test multiple times 
with same results.

Thus I think the problem is sorting the data in a shard.

Pawel Szczur commented on BEAM-315:

As far as I understand the issue there are 3 places it may originate from:
 1. windowing (all items should end up in one global pane)
 2. shuffle (is windowing considered during shuffle?)
 3. sorting items in a given shard (is sorting considered?)

Am I correct?

I thought about it. From your description I guess this should not be a real 
problem. As long as the corresponding values are compared using the same 
comparison function. In fact I think this was done on purpose to speed up the 
execution. 

First the values are shuffled according to hash function of the key and all the 
KV ends up in a correct buckets, then we need to sort them. I guess we compare 
encoded keys because there's no guarantee that pure keys have comparator 
defined and we have predefined bytes comparator.
