> Canary sink type cast error

> Project: HBase
> Issue Type: Bug
> Reporter: Chinmay Kulkarni
> Assignee: Chinmay Kulkarni
> Priority: Major

> When running the main method of Canary.java, we see the following error:
> Exception in thread "main" java.lang.ClassCastException:
> org.apache.hadoop.hbase.tool.Canary$RegionServerStdOutSink cannot be cast to
> org.apache.hadoop.hbase.tool.Canary$RegionStdOutSink
> at org.apache.hadoop.hbase.tool.Canary.newMonitor(Canary.java:911)
> at org.apache.hadoop.hbase.tool.Canary.run(Canary.java:796)
> at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:70)
> at org.apache.hadoop.hbase.tool.Canary.main(Canary.java:1571)
> This happens because we typecast the sink depending on the mode (zookeeper
> mode/region server mode) that Canary is configured in. In case no mode is
> specified, we typecast the sink into _RegionStdOutSink_. In general, it is
> possible to provide inconsistent mode and sink types while running Canary.
