Jean-Daniel Cryans created HBASE-6860:
-----------------------------------------
Summary: [replication] HBASE-6550 is too aggressive, DDOSes .META.
Key: HBASE-6860
URL: https://issues.apache.org/jira/browse/HBASE-6860
Project: HBase
Issue Type: Improvement
Reporter: Jean-Daniel Cryans
Priority: Blocker
Fix For: 0.94.2, 0.96.0
I was doing maintenance on clusters and rebooting a replication slave was
giving me a lot of issues because the master wasn't able to read .META. while
it was bombarded with getClosestRowBefore() coming from all the
ReplicationSinks. Since no regions are assigned, and it doesn't retry, it goes
straight back to the source which retries again.
Also it seems that in some cases with retries=1 we don't even recover from a
stale .META. cache.
