merrimanr commented on issue #1458: METRON-2177 Upgrade Profiler for HBase 2.0.2 URL: https://github.com/apache/metron/pull/1458#issuecomment-516178822 I ran through the testing instructions and hit some problems with the Batch Profiler. First error I ran into was this: ``` 19/07/29 21:47:31 INFO BatchProfilerCLI: Loading profiles from '/usr/metron/0.7.2/config/zookeeper/profiler.json' Exception in thread "main" com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of `org.apache.metron.common.configuration.profiler.ProfileResult` (although at least one Creator exists): no String-argument constructor/factory method to deserialize from String value ('count') at [Source: (String)"{ "profiles": [ { "profile": "hello-world", "foreach": "'global'", "init": { "count": "0" }, "update": { "count": "count + 1" }, "result": "count" } ], "timestampField": "timestamp" } "; line: 8, column: 18] (through reference chain: org.apache.metron.common.configuration.profiler.ProfilerConfig["profiles"]->java.util.ArrayList[0]->org.apache.metron.common.configuration.profiler.ProfileConfig["result"]) ``` The same `profiler.json` deserializes without issue in the integration tests. I suspect it is caused by a jackson version problem. When I update `profiler.json` to: ``` { "profiles": [ { "profile": "hello-world", "foreach": "'global'", "init": { "count": "0" }, "update": { "count": "count + 1" }, "result": { "profile": "count" } } ], "timestampField": "timestamp" } ``` I am able to get past that error but then I run into this error: ``` 19/07/29 21:50:42 INFO StateStoreCoordinatorRef: Registered StateStoreCoordinator endpoint Exception in thread "main" java.lang.IllegalAccessError: class org.apache.hadoop.hdfs.web.HftpFileSystem cannot access its superinterface org.apache.hadoop.hdfs.web.TokenAspect$TokenManagementDelegator at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:763) ```
