Hudson commented on HBASE-18762: -------------------------------- FAILURE: Integrated in Jenkins build HBase-1.4 #932 (See [https://builds.apache.org/job/HBase-1.4/932/]) HBASE-18762 Canary sink type cast error (apurtell: rev eace8b14b3443b61562c434d84ded51bb9843a56) * (edit) hbase-server/src/main/java/org/apache/hadoop/hbase/tool/Canary.java > 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 > Fix For: 2.0.0, 3.0.0, 1.4.0, 1.5.0 > > Attachments: HBASE-18762.001.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 (v6.4.14#64029)
