 Summary: Deadlock found in Flink Streaming job
 Key: FLINK-8020
 URL: https://issues.apache.org/jira/browse/FLINK-8020
 Project: Flink
  Issue Type: Bug
  Components: Kafka Connector, Streaming, Streaming Connectors
Affects Versions: 1.3.2
 Environment: Kafka 0.8.2 and Flink 1.3.2 on YARN mode
Reporter: Weihua Jiang
Priority: Blocker
 Attachments: jstack67976-2.log

Our streaming job run into trouble in these days after a long time smooth 
running. One issue we found is [#FLINK-8019] and another one is this one.

After analyzing the jstack, we believe  we found a DEAD LOCK in flink:
1. The thread "cache-process0 -> async-operator0 -> Sink: hbase-sink0 (8/8)" 
hold lock 0x0007b6aa1788 and is waiting for lock 0x0007b6aa1940.
2. The thread "Time Trigger for cache-process0 -> async-operator0 -> Sink: 
hbase-sink0 (8/8)" hold lock 0x0007b6aa1940 and is waiting for lock 
0x0007b6aa1788. 

This DEADLOCK made the job fail to proceed.

[jira] [Created] (FLINK-8021) End-to-end tests may not shutdown cluster on failure

 Summary: End-to-end tests may not shutdown cluster on failure
 Key: FLINK-8021
 URL: https://issues.apache.org/jira/browse/FLINK-8021
 Project: Flink
  Issue Type: Bug
  Components: Tests
Affects Versions: 1.4.0, 1.5.0
Reporter: Chesnay Schepler


In this job https://travis-ci.org/zentol/flink/jobs/298656917 the kafka E2E 
test failed straight away due to a missing class. The subsequent tests failed 
since they cannot allocate the JM port.

It is thus likely that the E2E tests do not shutdown the cluster in all failure 
cases.

For me they showed in user mailing list, but not in dev. (or maybe the 
reverse, not quite sure...)

 Summary: Provide configuration to enable/disable ability to cancel

 Key: FLINK-8031
 URL: https://issues.apache.org/jira/browse/FLINK-8031
 Project: Flink
  Issue Type: Improvement
  Components: flink-contrib
Affects Versions: 1.3.2
Reporter: Stephen Hesketh


The Web API can be configured to prevent job submission by setting 
jobmanager.web.submit.enable to false in the Flink YAML configuration file:

{quote}
\# Flag to specify whether job submission is enabled from the web-based
\# runtime monitor. Uncomment to disable.
{color:red}
jobmanager.web.submit.enable: false{color}
{quote}

However, users can still cancel running jobs. We would like to be able to offer 
the Web Frontend to teams for monitoring of jobs. However, since this is shared 
infrastructure we do not want users to be able to run or cancel jobs through 
this interface.

It is proposed that the ability to cancel jobs is also configurable in the 
Flink yaml configuration file.

- Put the following flink-conf.yaml:
{code}
high-availability: zookeeper
high-availability.storageDir: file:///tmp/flink-ha
high-availability.zookeeper.quorum: localhost:2181
high-availability.zookeeper.path.cluster-id: /my-namespace

- Start Flink, submit a job (any streaming example will do)

The job submission will time out. On the JobManager, it seems that the job 
submission gets stuck when trying to submit something to Zookeeper.

 Summary: Consider using gradle to build Flink
 Key: FLINK-8036
 URL: https://issues.apache.org/jira/browse/FLINK-8036
 Project: Flink
  Issue Type: Improvement
Reporter: Ted Yu


Here is summary from Lukasz over this thread 
(http://search-hadoop.com/m/Beam/gfKHFVh4NM151XIu1?subj=Re+DISCUSS+Move+away+from+Apache+Maven+as+build+tool)
 w.r.t. performance boost from using gradle:

Maven performs parallelization at the module level, an entire module needs
to complete before any dependent modules can start, this means running all
the checks like findbugs, checkstyle, tests need to finish. Gradle has task
level parallelism between subprojects which means that as soon as the
compile and shade steps are done for a project, and dependent subprojects
can typically start. This means that we get increased parallelism due to
not needing to wait for findbugs, checkstyle, tests to run. I typically see
~20 tasks (at peak) running on my desktop in parallel.

Flink should consider using gradle - on Linux with SSD, a clean build takes an 
hour.

{code:sql}
SELECT
  MAP['key1', f0, 'key2', f1] AS stringKeyedMap,
  MAP['key', 'value'] AS literalMap,
  MAP[f0, f1] AS fieldMap
FROM
  table
{code}
