Ravi, Thank you so much! It works. A few things I have observed: 1. In connect string, instance needs to be separated from server. sqoop list-tables -libjars "/usr/hdp/2.2.8.0-3150/sqoop/lib/jtds-1.3.1.jar" --driver "net.sourceforge.jtds.jdbc.Driver" --connect "jdbc:jtds:sqlserver://xxx.xxx.xxx.xxx;instance=yyyy;databaseName=zzzz;domain=ad" --username xxxxxx --password 'xxxxxx' is the correct format 2. list-tables only list physical tables. Views are not listed 3. When import from MS SQL Server to Hive table. Data type may be changed by default. I see date/datetime is changed to string, bit is changed to boolean. Overall, it works very well. ... View more
