Gary Yao created FLINK-10435:
--------------------------------
Summary: Client sporadically hangs after Ctrl + C
Key: FLINK-10435
URL: https://issues.apache.org/jira/browse/FLINK-10435
Project: Flink
Issue Type: Bug
Components: Client, YARN
Affects Versions: 1.7.0, 1.6.2, 1.5.5
Reporter: Gary Yao
Fix For: 1.7.0, 1.6.2, 1.5.5
When submitting a YARN job cluster in attached mode, the client hangs
indefinitely if Ctrl + C is pressed at the right time. One can recover from
this by sending SIGKILL.
*Command to submit job*
{code}
HADOOP_CLASSPATH=`hadoop classpath` bin/flink run -m yarn-cluster
examples/streaming/WordCount.jar
{code}
*Output/Stacktrace*
{code}
