Daniel Halperin updated BEAM-747:
---------------------------------
Description:
Example 1:
https://builds.apache.org/job/beam_PreCommit_MavenVerify/3934/org.apache.beam$beam-examples-java/console
Here it looks like we need to retry listing files, at least a little bit, if
none are found. They did show up:
{code}
gsutil ls
gs://temp-storage-for-end-to-end-tests/WordCountIT-2016-10-13-12-37-02-467/output/results\*
gs://temp-storage-for-end-to-end-tests/WordCountIT-2016-10-13-12-37-02-467/output/results-00000-of-00003
gs://temp-storage-for-end-to-end-tests/WordCountIT-2016-10-13-12-37-02-467/output/results-00001-of-00003
gs://temp-storage-for-end-to-end-tests/WordCountIT-2016-10-13-12-37-02-467/output/results-00002-of-00003
{code}
Example 2:
https://builds.apache.org/job/beam_PostCommit_MavenVerify/org.apache.beam$beam-examples-java/1525/testReport/junit/org.apache.beam.examples/WordCountIT/testE2EWordCount/
Here it looks like we need to fill in the shard template if the filesystem does
not give us a consistent result:

We missed shard 1-of-3 and hence got the wrong checksum.
