--------------------------------------
Summary: Topology aware block replication strategies
Key: SPARK-15354
URL: https://issues.apache.org/jira/browse/SPARK-15354
Project: Spark
Issue Type: Sub-task
Components: Mesos, Spark Core, YARN
Reporter: Shubham Chopra
Implementations of strategies for resilient block replication for different
resource managers that replicate the 3-replica strategy used by HDFS, where the
first replica is on an executor, the second replica within the same rack as the
executor and a third replica on a different rack.
The implementation involves providing two pluggable classes, one running in the
driver that provides topology information for every host at cluster start and
the second prioritizing a list of peer BlockManagerIds.
