---------------------------------
Summary: Bug in Hybrid Hash Join: Request to spill a partition
with less than two buffers.
Key: FLINK-2763
URL: https://issues.apache.org/jira/browse/FLINK-2763
Project: Flink
Issue Type: Bug
Components: Distributed Runtime
Affects Versions: master
Reporter: Greg Hogan
The following exception is thrown when running the example triangle listing
with an unmodified master build (4cadc3d6).
{noformat}
./bin/flink run
~/flink-examples/flink-java-examples/target/flink-java-examples-0.10-SNAPSHOT-EnumTrianglesOpt.jar
~/rmat/undirected/s19_e8.ssv output
{noformat}
The only changes to {{flink-conf.yaml}} are {{taskmanager.numberOfTaskSlots:
8}} and {{parallelism.default: 8}}.
I have confirmed with input files
[s19_e8.ssv|https://drive.google.com/file/d/0B6TrSsnHj2HxR2lnMHR4amdyTnM/view?usp=sharing]
(40 MB) and
[s20_e8.ssv|https://drive.google.com/file/d/0B6TrSsnHj2HxNi1HbmptU29MTm8/view?usp=sharing]
(83 MB). On a second machine only the larger file caused the exception.
