Brahma Reddy Battula created HDFS-9917:
------------------------------------------
Summary: IBR accumulate more objects when SNN was down for
sometime.
Key: HDFS-9917
URL: https://issues.apache.org/jira/browse/HDFS-9917
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Brahma Reddy Battula
Assignee: Brahma Reddy Battula
SNN was down for sometime because of some reasons..After restarting SNN,it
became unreponsive because
- 29 DN's sending IBR in each 5 million ( most of them are delete IBRs), where
as each datanode had only ~2.5 million blocks.
- GC can't trigger on this objects since all will be under RPC queue.
To recover this( to clear this objects) ,restarted all the DN's one by
one..This issue happened in 2.4.1 where split of blockreport was not available.
