Subject Re: High get/scan rates on HBase table even if no readers are on
Date Tue, 08 Dec 2015 08:17:54 GMT
We had a similar issue a while ago, and it was HBase Canary on each
region server scanning hbase:meta region every few seconds. You can
try disabling "HBase Canary" on Cloudera Manager configuration page
and restarting the servers.

But if you don't wish to restart for some reason, manually killing
Canary processes (org.apache.hadoop.hbase.tool.Canary) will do.
Note that we had to kill their parent processes first to prevent
respawning.

To see which regions are currently being accessed, you might want
to check out tools like hbase-region-inspector.
