将 java 客户端升级到 2.2.2 后创建 hbase 表实例时出错

Question

An application that accesses hbase is producing an error on attempting to create an instance of an hbase table. This used to work fine but the hbase server was upgraded and subsequently I was forced to update the java client.

Exception in thread "main" java.lang.NoClassDefFoundError: 
org/apache/commons/lang3/NotImplementedException
at 
org.apache.hadoop.hbase.client.ConnectionImplementation$2.build(ConnectionImplementation.java:375)
at org.apache.hadoop.hbase.client.Connection.getTable(Connection.java:106)
at 
org.apache.hadoop.hbase.client.ConnectionImplementation.getTable(ConnectionImplementation.java:366)

The above error occurs on the following line:

hTable_Test = conn.getTable(TableName.valueOf("test:test_messages"));

I don't understand what the issue is. Can someone please help verify what this error means?

Answer 1

NoClassDefFoundError means that at runtime you don't have java class which was available at compile time.
org/apache/commons/lang3/NotImplementedException comes with group: 'org.apache.commons', name: 'commons-lang3', version: 'some version'
Can you check if you have this jar file in your execution environment?
