hive.HiveImport: FAILED: SemanticException [Error 10072]: Database does not exist:

I am trying to import MySQL database into Hive to analysis of large MySQL Data according to Blog there are couple of ways to do this


  1. Non realtime: Sqoop

  2. Realtime: Hadoop Applier for MySQL



so I decided to go with the 'Non realtime' approach and I have setup the Hadoop cluster with 4 node, Sqoop and Hive which working fine with following versions

Name Version

Apache Hadoop 2.6.0

Apache Hive hive-0.14.0

Apache Sqoop sqoop-1.4.5.bin__hadoop-2.0.4-alpha

Now when I am trying to import data using following command

Import Command

sqoop-import-all-tables --verbose --connect jdbc:mysql://X.X.X.X/edgeowt --username root -P --hive-import --warehouse-dir /user/hive/warehouse --hive-database edgeowt.db --hive-overwrite


then I am getting following error

Error

INFO hive.HiveImport: FAILED: SemanticException [Error 10072]: Database does not exist: edgeowt.db
15/04/16 13:32:09 ERROR tool.ImportAllTablesTool: Encountered IOException running import job: java.io.IOException: Hive exited with status 88


I logged in with Hiveserver2 and check the database, but I can able to see the given database

$HIVE_HOME/bin>beeline
beeline> !connect jdbc:hive2://localhost:10000 scott tiger org.apache.hive.jdbc.HiveDriver
0: jdbc:hive2://localhost:10000> show databases;
+----------------+--+
| database_name |
+----------------+--+
| default |
| edgeowt |
+----------------+--+


After looking into HDFS file System web interface I realize that the Owner of the DB is different

Permission Owner Group Size Replication Block Size Name
drwxr-xr-x hduser supergroup 0 B 0 0 B candidate
drwxr-xr-x scott supergroup 0 B 0 0 B edgeowt.db
drwxr-xr-x scott supergroup 0 B 0 0 B hd_temperature


as I am trying to import the data using hduser and and the database is created using scott user.
I tried to grant ALL previlages to hduser on edgeowt.db using following command

0: jdbc:hive2://localhost:10000>GRANT ALL ON DATABASE edgeowt TO USER hduser;


and check with

0: jdbc:hive2://localhost:10000> SHOW GRANT ON DATABASE edgeowt;
+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+----------------+----------+--+
| database | table | partition | column | principal_name | principal_type | privilege | grant_option | grant_time | grantor |
+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+----------------+----------+--+
| edgeowt | | | | admin | ROLE | ALL | false | 1429170366000 | scott |
| edgeowt | | | | hduser | USER | ALL | false | 1429170906000 | scott |
+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+----------------+----------+--+


but unable to solve the error , So how can I solve this problem ? or any point to solve this will be helpful.

EDIT

tried with following command still having same error

sqoop-import-all-tables --verbose --connect jdbc:mysql://X.X.X.X/edgeowt --username root -P --hive-import --warehouse-dir /user/hive/warehouse --hive-database edgeowt --hive-overwrite

Answer

Finally I got the answer by myself while reading the forum discussion about the same issue here.

The issue was with the Hive Metastore configuration, there are three types of Hive Metastore configurations

  1. Embedded Metastore (default metastore deployment mode).
  2. Locall Metastore.
  3. Remote Metastore.

and my Hive Metastore configuration was the default one. As mention in cloudera documentation of Configuring the Hive Metastore, I change the metastore configuration from Embedded (Default) to Remote Metastore and its start working for me.

for More information of Metastore configuration use following documentation of Cloudera.

Configuring the Hive Metastore

Sqoop Command

sqoop-import-all-tables --connect jdbc:mysql://X.X.X.X/edgeowt --username root -P --hive-import --hive-database edgeowt --hive-overwrite -m 4
