------------------------------------
Summary: Enable optimized block reports
Key: HDFS-8867
URL: https://issues.apache.org/jira/browse/HDFS-8867
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.7.0
Reporter: Rushabh S Shah
Assignee: Daryn Sharp
Fix For: 2.7.2
Opening this ticket on behalf of [~daryn]
HDFS-7435 introduced a more efficiently encoded block report format designed to
improve performance and reduce GC load on the NN and DNs. The NN is not
advertising this capability to the DNs so old-style reports are still being
used.
