Hi,all： 最近在升级flink1.11，sql中用到hbase connctor，发布到yarn-session时，报如下异常： 2020-07-29 11:49:55 org.apache.hadoop.hbase.DoNotRetryIOException: java.lang.NoClassDefFoundError: Could not initialize class org.apache.hadoop.hbase.util.ByteStringer at org.apache.hadoop.hbase.client.RpcRetryingCaller.translateException(RpcRetryingCaller.java:248) at org.apache.hadoop.hbase.client.RpcRetryingCaller.callWithoutRetries(RpcRetryingCaller.java:221) at org.apache.hadoop.hbase.client.ScannerCallableWithReplicas$RetryingRPC.call(ScannerCallableWithReplicas.java:388) at org.apache.hadoop.hbase.client.ScannerCallableWithReplicas$RetryingRPC.call(ScannerCallableWithReplicas.java:362) at org.apache.hadoop.hbase.client.RpcRetryingCaller.callWithRetries(RpcRetryingCaller.java:142) at org.apache.hadoop.hbase.client.ResultBoundedCompletionService$QueueingFuture.run(ResultBoundedCompletionService.java:80) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: java.lang.NoClassDefFoundError: Could not initialize class org.apache.hadoop.hbase.util.ByteStringer at org.apache.hadoop.hbase.protobuf.RequestConverter.buildRegionSpecifier(RequestConverter.java:1053) at org.apache.hadoop.hbase.protobuf.RequestConverter.buildScanRequest(RequestConverter.java:496) at org.apache.hadoop.hbase.client.ScannerCallable.openScanner(ScannerCallable.java:402) at org.apache.hadoop.hbase.client.ScannerCallable.call(ScannerCallable.java:274) at org.apache.hadoop.hbase.client.ScannerCallable.call(ScannerCallable.java:62) at org.apache.hadoop.hbase.client.RpcRetryingCaller.callWithoutRetries(RpcRetryingCaller.java:219) ... 7 more
注意到官方文档有Note: Note: To use HBase connector in SQL Client or Flink cluster, it’s highly recommended to add HBase dependency jars to Hadoop classpath. Flink will load all jars under Hadoop classpath automatically, please refer to HBase, MapReduce, and the CLASSPATH<https://hbase.apache.org/book.html#hbase.mapreduce.classpath> about how to add HBase dependency jars to Hadoop classpath. 但是在yarn session下怎么设置classpath呢
