java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient

原因:

這是因為沒有啟動元數據庫

解決方案:

hive --service metastore

關閉hiveserver2

然后重新啟動hiveserver2

注意:

啟動的順序必須是先metastore然后是hiveserver2

如果出現上述報錯，必須關閉hiveserver2后重新啟動hiveserver2

否則會導致metastore在hiveserver2啟動后才啟動，那么此時hiveserver2就無法監聽10000端口，導致beeline無法正常連接元數據庫了。
