今天有同事在配置PostgreSQL為Hive元數(shù)據(jù)庫后，運行Hive SQL時遇到以下報錯信息：

Caused by: MetaException(message:Got exception: org.apache.hadoop.hive.metastore.api.MetaException javax.jdo.JDODataStoreException: Error executing JDOQL query “SELECT “THIS”.”NAME” AS NUCORDER0 FROM “DBS” “THIS” WHERE (LOWER(“THIS”.”NAME”) LIKE ? ESCAPE ‘\’ ) ORDER BY NUCORDER0 ” : ERROR: invalid escape string
Hint: Escape string must be empty or one character..
