Gavin updated HBASE-18762: -------------------------- Comment: was deleted (was: A comment with security level 'jira-users' was removed.) > Canary sink type cast error > --------------------------- > > Key: HBASE-18762 > URL: https://issues.apache.org/jira/browse/HBASE-18762 > Project: HBase > Issue Type: Bug > Reporter: Chinmay Kulkarni > Assignee: Chinmay Kulkarni > Priority: Major > Fix For: 1.4.0, 2.0.0 > > Attachments: HBASE-18762.001.patch, HBASE-18830-addendum.patch > > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
