Subject Re: Using S3 as state backend
Date Tue, 15 Dec 2015 15:52:58 GMT
Sure, excuse me if anything was obvious or wrong, I know next to nothing
about Hadoop.

1. get the Hadoop 2.7 distribution (I set its path to HADOOP_HOME to make
things easier for mysellf)
2. set the HADOOP_CLASSPATH to include
${HADOOP_HOME}/share/hadoop/common/*:${HADOOP_HOME}/share/hadoop/tools/lib/*
(you may not need all those paths?)
3. stick this into $HADOOP_HOME/etc/hadoop/core-site.xml

<configuration>
  <property>
    <name>fs.defaultFS</name>
    <value>s3a://YOUR-BUCKET</value>
  </property>
  <property>
    <name>fs.s3a.impl</name>
    <value>org.apache.hadoop.fs.s3a.S3AFileSystem</value>
  </property>
</configuration>

4. stick this into your flink-conf

fs.hdfs.hadoopconf: $HADOOP_HOME/etc/hadoop
recovery.mode: zookeeper
recovery.zookeeper.quorum: whatever01.local:2181
recovery.zookeeper.path.root: /whatever
state.backend: filesystem
state.backend.fs.checkpointdir: s3a:///YOUR-BUCKET/checkpoints
recovery.zookeeper.storageDir: s3a:///YOUR-BUCKET/recovery

That's all I had to do in the Flink side. obvs in the AWS side, I had my
IAM role setup with readlwrite access to the bucket.

Thanks,
Brian
