------------------------------------------
Summary: piggyback incremental cache reports on DN heartbeats
Key: HDFS-5092
URL: https://issues.apache.org/jira/browse/HDFS-5092
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Colin Patrick McCabe
Priority: Minor
We should send incremental cache reports as part of DN heartbeats, similar to
how we do incremental block reports. Then we would only need to send full
cache reports rarely (again similar to full block reports).
