@jsensharma  There is a option like postgresql on MariaDB what you said. https://mariadb.com/kb/en/library/sql-mode/#sql_mode-values   So, I setted sql_mode option in my.cnf like this and restarted MariaDB, hive-metastore and hive-server2.     [mysqld] ... sql_mode=NO_BACKSLASH_ESCAPES ...     Than it showed me different exception again. I was sure query what hive ran was fine when I watched run query. Because this query already conciderated backslash escape character. So I removed sql_mode option and restarted MariaDB, hive-metastore and hive-server2 again. Than it didn't show any exception anymore. I don't have any idea what is different. Anyway this problem was gone and my hive-client has connected my MariaDB well.     Caused by: java.sql.SQLException: Incorrect arguments to ESCAPE Query is: SELECT A0.TBL_NAME AS NUCORDER0 FROM TBLS A0 LEFT OUTER JOIN DBS B0 ON A0.DB_ID = B0.DB_ID WHERE B0.`NAME` = ? AND LOWER(A0.TBL_NAME) LIKE '_%' ESCAPE '\\' ORDER BY NUCORDER0, parameters ['default'] java thread: pool-5-thread-2 at org.mariadb.jdbc.internal.util.LogQueryTool.exceptionWithQuery(LogQueryTool.java:163) at org.mariadb.jdbc.internal.protocol.AbstractQueryProtocol.executeQuery(AbstractQueryProtocol.java:280) at org.mariadb.jdbc.MariaDbPreparedStatementClient.executeInternal(MariaDbPreparedStatementClient.java:223) ... 37 more       ...
