------------------------------
Summary: Exception happened in case set
hive.metastore.try.direct.sql to true when running 'show table stats xxx' on
impala with hive metastore db is mysql
Key: HIVE-8824
URL: https://issues.apache.org/jira/browse/HIVE-8824
Project: Hive
Issue Type: Bug
Components: Metastore
Affects Versions: 0.13.1
Reporter: lixuebin
First:
set hive-site.xml hive.metastore.try.direct.sql true
second:
On impala
show table stats xxxxx;
Remark:
MYSQL does not support table name and column name with double quotes, such as :
select * from "testtb" where "id"='1234';
should be: select * from testtb where id='1234';
MetaStoreDirectSql.java should be checked.
The Exception:
metastore.ObjectStore (ObjectStore.java:handleDirectSqlError(2243)) - Direct
SQL failed, falling back to ORM
javax.jdo.JDODataStoreException: Error executing SQL query "select
"COLUMN_NAME", "COLUMN_TYPE", "LONG_LOW_VALUE", "LONG_HIGH_VALUE",
"DOUBLE_LOW_VALUE", "DOUBLE_HIGH_VALUE", "BIG_DECIMAL_LOW_VALUE",
"BIG_DECIMAL_HIGH_VALUE", "NUM_NULLS", "NUM_DISTINCTS", "AVG_COL_LEN",
"MAX_COL_LEN", "NUM_TRUES", "NUM_FALSES", "LAST_ANALYZED" from "TAB_COL_STATS"
where "DB_NAME" = ? and "TABLE_NAME" = ? and "COLUMN_NAME" in (?)".
