Ted Yu created HBASE-19898:
------------------------------
Summary: Canary should choose RegionStdOutSink automatically when
write sniffing is specified
Key: HBASE-19898
URL: https://issues.apache.org/jira/browse/HBASE-19898
Project: HBase
Issue Type: Bug
Reporter: Ted Yu
Currently RegionServerStdOutSink is instantiated by default, even if user
specifies -writeSniffing on the command line.
Write sniffing would be ignored since Sink instance is of
RegionServerStdOutSink class:
{code}
if (this.sink instanceof RegionServerStdOutSink || this.regionServerMode) {
monitor =
new RegionServerMonitor(connection, monitorTargets, this.useRegExp,
(StdOutSink) this.sink, this.executor,
this.regionServerAllRegions,
this.treatFailureAsError);
{code}
RegionStdOutSink should be used for write sniffing.
