Hi All,
I am working with HBase-Phoenix, *everything works fine*. In addition trying to enable Tracing <https://phoenix.apache.org/tracing.html> in Phoenix with the following steps, 1. Copy ‘hadoop-metrics2-hbase.PROPERTIES’ from Phoenix package to HBase conf folder. 2. ‘hadoop-metrics2-phoenix.PROPERTIES’ file will be in ‘Phoenix/bin’ location by default. So I left it as it is. 3. Add the following property to phoenix configuration, <property> <name>phoenix.trace.frequency</name> <value>always</value> </property> After doing the above, HBase’s HMaster fails to start with the following exception; Please tell if you have any suggestion on this, 2017-11-08 16:46:56,118 INFO [main] regionserver.RSRpcServices: master/Selfuser-VirtualBox/172.16.203.117:60000 server-side HConnection retries=140 2017-11-08 16:46:56,520 INFO [main] ipc.SimpleRpcScheduler: Using deadline as user call queue, count=3 2017-11-08 16:46:56,554 INFO [main] ipc.RpcServer: master/Selfuser-VirtualBox/192.16.203.117:60000: started 10 reader(s) listening on port=60000 *2017-11-08 16:46:56,839 INFO [main] impl.MetricsConfig: loaded properties from hadoop-metrics2-hbase.properties* *2017-11-08 16:46:56,926 INFO [main] trace.PhoenixMetricsSink: Writing tracing metrics to phoenix table* *2017-11-08 16:46:56,933 ERROR [main] master.HMasterCommandLine: Master exiting* *java.lang.RuntimeException: Failed construction of Master: class org.apache.hadoop.hbase.master.HMaster. * * at org.apache.hadoop.hbase.master.HMaster.constructMaster(HMaster.java:2512)* at org.apache.hadoop.hbase.master.HMasterCommandLine.startMaster(HMasterCommandLine.java:231) at org.apache.hadoop.hbase.master.HMasterCommandLine.run(HMasterCommandLine.java:137) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:70) at org.apache.hadoop.hbase.util.ServerCommandLine.doMain(ServerCommandLine.java:126) at org.apache.hadoop.hbase.master.HMaster.main(HMaster.java:2522) Caused by: java.lang.AbstractMethodError: org.apache.phoenix.trace.PhoenixMetricsSink.init(Lorg/apache/commons/configuration/SubsetConfiguration;)V at org.apache.hadoop.metrics2.impl.MetricsConfig.getPlugin(MetricsConfig.java:199) at org.apache.hadoop.metrics2.impl.MetricsSystemImpl.newSink(MetricsSystemImpl.java:530) at org.apache.hadoop.metrics2.impl.MetricsSdrddystemImpl.configureSinks(MetricsSystemImpl.java:502) at org.apache.hadoop.metrics2.impl.MetricsSystemImpl.configure(MetricsSystemImpl.java:481) at org.apache.hadoop.metrics2.impl.MetricsSystemImpl.start(MetricsSystemImpl.java:189) at org.apache.hadoop.metrics2.impl.MetricsSystemImpl.init(MetricsSystemImpl.java:164) at org.apache.hadoop.metrics2.lib.DefaultMetricsSystem.init(DefaultMetricsSystem.java:54) at org.apache.hadoop.metrics2.lib.DefaultMetricsSystem.initialize(DefaultMetricsSystem.java:50) at org.apache.hadoop.hbase.metrics.BaseSourceImpl$DefaultMetricsSystemInitializer.init(BaseSourceImpl.java:49) at org.apache.hadoop.hbase.metrics.BaseSourceImpl.<init>(BaseSourceImpl.java:72) at org.apache.hadoop.hbase.ipc.MetricsHBaseServerSourceImpl.<init>(MetricsHBaseServerSourceImpl.java:66) at org.apache.hadoop.hbase.ipc.MetricsHBaseServerSourceFactoryImpl.getSource(MetricsHBaseServerSourceFactoryImpl.java:48) at org.apache.hadoop.hbase.ipc.MetricsHBaseServerSourceFactoryImpl.create(MetricsHBaseServerSourceFactoryImpl.java:38) at org.apache.hadoop.hbase.ipc.MetricsHBaseServer.<init>(MetricsHBaseServer.java:40) at org.apache.hadoop.hbase.ipc.RpcServer.<init>(RpcServer.java:2040) at org.apache.hadoop.hbase.regionserver.RSRpcServices.<init>(RSRpcServices.java:930) at org.apache.hadoop.hbase.master.MasterRpcServices.<init>(MasterRpcServices.java:231) at org.apache.hadoop.hbase.master.HMaster.createRpcServices(HMaster.java:572) at org.apache.hadoop.hbase.regionserver.HRegionServer.<init>(HRegionServer.java:531) at org.apache.hadoop.hbase.master.HMaster.<init>(HMaster.java:412) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:526) at org.apache.hadoop.hbase.master.HMaster.constructMaster(HMaster.java:2505) ... 5 more Note: Additionally based on this Hortonworks reference <https://community.hortonworks.com/articles/92371/trace-logging-for-phoenix.html>, did the following changes in log4j.PROPERTIES of Phoenix. Still facing same issue; log4j.threshold=TRACE log4j.logger.org.apache.phoenix=TRACE log4j.logger.org.apache.hadoop.hbase.ipc=TRACE log4j.logger.org.apache.hadoop.hbase.ipc.RegionCoprocessorRpcChannel=DEBUG -- Thanks and regards D.Mallieswari
