Spark integrated hive encounters MySQL check failure

Source: Internet
Author: User

Questions:
Spark integrated Hive, when starting Spark-shell or Spark-sql, error:

noton mysql: atline15.  "@" (64after"".

Environment:
spark-1.4
hive-1.2.1
mysql-5.1
JDBC Driver

Reason:
See how Hive's Source Metastoredirectsql is constructed:

  publicMetaStoreDirectSql(PersistenceManager pm) {    this.pm = pm;    Transaction tx = pm.currentTransaction();    tx.begin();    booleanfalse;    try {      trySetAnsiQuotesForMysql();      true;    catch (SQLException sqlEx) {      LOG.info("MySQL check failed, assuming we are not on mysql: " + sqlEx.getMessage());      tx.rollback();      tx = pm.currentTransaction();      tx.begin();    }

where Metastoredirectsql.trysetansiquotesformysql () is called, the code sets Sql_mode:

SET @@session.sql_mode=ANSI_QUOTES

When MySQL's JDBC driver executes execute (SQL), it first checks the statement and then reports encountered: "@" (64) is wrong.
