Hello, I'm trying to use HBase on one of my stream transformations and I'm running into the Guava/Stopwatch dependency problem
java.lang.IllegalAccessError: tried to access method com.google.common.base.Stopwatch.<init>()V from class org.apache.hadoop.hbase.zookeeper.MetaTableLocator Reading on the problem it seems that there is a way to avoid it using shading: https://ci.apache.org/projects/flink/flink-docs-release-1.1/setup/building.html#dependency-shading But I can't get it to work. I followed the documented steps and it builds but when I try to run the newly built version it fails when trying to connect to the Resource Manager: 2017-01-17 00:42:05,872 INFO org.apache.flink.yarn.YarnClusterDescriptor - Using values: 2017-01-17 00:42:05,872 INFO org.apache.flink.yarn.YarnClusterDescriptor - TaskManager count = 4 2017-01-17 00:42:05,873 INFO org.apache.flink.yarn.YarnClusterDescriptor - JobManager memory = 1024 2017-01-17 00:42:05,873 INFO org.apache.flink.yarn.YarnClusterDescriptor - TaskManager memory = 32768 2017-01-17 00:42:05,892 INFO org.apache.hadoop.yarn.client.RMProxy - Connecting to ResourceManager at /0.0.0.0:8032 2017-01-17 00:42:07,023 INFO org.apache.hadoop.ipc.Client - Retrying connect to server: 0.0.0.0/0.0.0.0:8032. Already tried 0 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1000 MILLISECONDS) 2017-01-17 00:42:08,024 INFO org.apache.hadoop.ipc.Client - Retrying connect to server: 0.0.0.0/0.0.0.0:8032. Already tried 1 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1000 MILLISECONDS) I'm currently building version 1.1.4 of Flink based on the github repo. Building it without shading (not executing `mvn clean install` on the flink-dist sub-project) works fine until I try to use HBase, at which point I get the Stopwatch exception. Has anyone been able to solve this?
