[jira] [Updated] (HBASE-18762) Canary sink type cast error
[ https://issues.apache.org/jira/browse/HBASE-18762?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Chinmay Kulkarni updated HBASE-18762:
-------------------------------------
Description:
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.
