Optional flush provokes periodic large spike in cluster traffic
---------------------------------------------------------------
Key: HBASE-774
URL: https://issues.apache.org/jira/browse/HBASE-774
Project: Hadoop HBase
Issue Type: Bug
Reporter: stack
Attachments: network.gif
Looking at our 70-node cluster, whose current state is mostly read-only but for
a service that is trickling in pages at about 5/600 an hour, network traffic
goes through the roof every 30 minutes. This is 0.1.3. Regionserver logs are
silent but for the optional flush that runs every 30 minutes. The optional
flush will put a few small files out on the filesystem tripping compactions of
small files.
