Description

Currently, BaseHoodieWriteClient contains schema evolution methods such as

• addColumn
• deleteColumns
• renameColumn
• updateColumnNullability
• updateColumnType
• updateColumnComment
• reOrderColPosition

These methods are not covered with tests and contain two issues:

1. Lost operation field in avro schema
2. Not found schema for table

   org.apache.hudi.exception.HoodieException: cannot find schema for current table: /tmp/hudi
   	at org.apache.hudi.client.BaseHoodieWriteClient.getInternalSchemaAndMetaClient(BaseHoodieWriteClient.java:1767)
   	at org.apache.hudi.client.BaseHoodieWriteClient.addColumn(BaseHoodieWriteClient.java:1673)
   	at org.apache.hudi.sink.TestWriteCopyOnWrite.test(TestWriteCopyOnWrite.java:454)
