Thank you very much for your response,
A) When I run command show tables it doesn't show newhive table.B) Yes the the newhive directory is present into /user/hive/warehouse and also containing the values imported from RDBMS
Please suggest and give me an example for the sqoop import command according to you for this case.
A) Here is the command
describe formatted letstry;
# col_name data_type comment
rollno int None
name string None
numbr int None
sno int None
# Detailed Table Information

B) hadoop dfs -ls /user/hive/warehouse/letstry/
Found 1 items

The first issue (sqoop one).
1) Is the table newhive coming when you list tables using 'show table'?
2) Are you seeing a directory 'newhive' in your hive warte house dir(usually /usr/hive/warehouse)?
If not sqoop is failing to create hive tables /load data into them. Only sqoop import to hdfs is getting successful the hive part is failing.
If hive in stand alone mode works as desired you need to check the sqoop configurations.
Regarding the second issue, can you check the storage location of NewTable and check whether there are files within. If so then do a 'cat' of those files and see whether it has the correct data format.
You can get the location of your table from the following command
describe formatted NewTable;
