報錯:
org.apache.hadoop.hive.metastore.HiveMetaException: Failed to get schema version.
Underlying cause: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException : Communications link failure
解決方案:
嘗試一:javax.jdo.option.ConnectionURL的值修改為:jdbc:mysql://node1:3306/hive3?createDatabaseIfNotExist=true&useSSL=false&useUnicode=true&characterEncoding=UTF-8
嘗試二:數字密碼123456變為"123456"
