Subject Re: [VOTE] Release Apache Flink 1.1.4 (RC3)
Date Fri, 16 Dec 2016 09:43:49 GMT
I'm not sure if we can release the release candidate like this, because I'm
running into two issues probably related to a recent rocksdb version
upgrade.

This is my list of points so far:

- Checked the staging repository. Quickstarts and Hadoop 1 / 2 are okay.
- Build a job against the staging repository
- Binaries deploy on a kerberized HA YARN / HDFS setup. Ran the KMeans and
WordCount batch jobs
- Executed a heavy, misbehaved streaming job for a few hours. While running
that job, I found that:
  - Not all checkpoint directories are cleaned up in HDFS (I use the async
rocksdb statebackend)
  -  segfaults from rocksdb (8 segfaults in ~3 hrs, but they were all
happening in the last minutes)
  - "beyond physical memory limits" container killings from YARN (I know we
can configure this, I just wonder what if we should change the default
value)
  -  the segfaults and memory limits caused the job to not run anymore in
the end because it was in a constant retry loop.
  - This is not a blocking issue I found during the testing:
https://issues.apache.org/jira/browse/FLINK-5345
  - This is also a non blocking issue for 1.1.4 (fixed for 1.2)
https://issues.apache.org/jira/browse/FLINK-4631


Let me know if we should release anyways or fix these issues first.
