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;
