Hi Yogesh

No issues seen on the first look. Can you run the sqoop import with --verbose option and post
in the console dump?

Are you having multiple hive installation? If so please verify whether you are using the same
hive for both SQOOP import and then for verifying data using hive cli. (the hive installation
@ HADOOP/hive)

Regards
Bejoy KS

Hi

I have created a table in Mysql by name Dummy and it has 2 columns, and 1 row of data

I want to upload that table into Hive using Sqoop tool.
I used this command  


sqoop import --connect jdbc:mysql://localhost:3306/Demo --username sqoop1 --password SQOOP1
-table Dummy --hive-table dummyhive  --create-hive-table  --hive-import --hive-home HADOOP/hive


The table has been succesfully uploaded into HDFS  /user/hive/warehouse
but when I run command in Hive 

Show Tables;

I don't find dummyhive table in it.

Please suggest and Help


Details of the command and output

mediaadmins-iMac-2:hive mediaadmin$ sqoop import --connect jdbc:mysql://localhost:3306/Demo
--username sqoop1 --password SQOOP1 -table Dummy --hive-table dummyhive  --create-hive-table 
--hive-import --hive-home HADOOP/hive
