Tank created FLINK-15216:
----------------------------
Summary: Can't use rocksdb with hdfs filesystem with
flink-s3-fs-hadoop
Key: FLINK-15216
URL: https://issues.apache.org/jira/browse/FLINK-15216
Project: Flink
Issue Type: Bug
Components: FileSystems
Affects Versions: 1.9.0
Reporter: Tank
Setup:
Flink 1.9.0 packaged with EMR 5.28 (uses hadoop 2.8.5)
After adding flink-s3-fs-hadoop to the plugins or libs directory, I was not
able to use rocksdb with hdfs filesystem.
To replicate:
Add rocksdb checkpoint & savepoint configuration to
/etc/flink/conf/flink-conf.yaml
state.backend: rocksdb
state.backend.incremental: true
state.savepoints.dir: hdfs://<path>savepoints/
state.checkpoints.dir: hdfs://<path>/checkpoints/
copy flink-s3-fs-hadoop to plugins directory
{{cp ./opt/flink-s3-fs-hadoop-1.9.0.jar ./plugins/s3-fs-hadoop/}}
Start any job:
flink run -m yarn-cluster -yid ${app_id} -yn 1 -p 1
/usr/lib/flink/examples/streaming/WordCount.jar
Looks like the hadoop classes packaged in flink-s3-fs-hadoop are interfering
with flink runtime.
