Hadoop Security configuration related with hive and sqoop - hadoop

Question

I'm using sqoop-1.4.6 to import data from MSSQL to hadoop-2.7.1
Using sqoop itself I can successfully list the table in MSSQL which mean it works fine. But when I tried to import to hadoop, following error message raised:
ERROR tool.ImportTool: Encountered IOException running import job: org.apache.hadoop.ipc.RemoteException(java.io.IOException): File /tmp/libjars/opencsv-2.3.jar could only be replicated to 0 nodes instead of minReplication (=1). There are 3 datanode(s) running and 3 node(s) are excluded in this operation.

So I check the log file of datanode, it gave the following infomation:
org.apache.hadoop.hdfs.server.datanode.DataNode: Failed to read expected encryption handshake from client. Perhaps the client is running an older version of Hadoop which does not support encryption.
Any idea how to change the configuration or how to deal with this problem?
Update:
It turns out that after I changed some configuration file, that problem begins. And the problem is not only about sqoop but hive has the same problem.
Configuration that I changed:
core-site.xml
<property>
<name>hadoop.rpc.protection</name>
<value>privacy</value>
</property>
hdfs-site.xml
<property>
<name>dfs.encrypt.data.transfer</name>
<value>true</value>
</property>
<property>
<name>dfs.encrypt.data.transfer.cipher.suites</name>
<value>AES/CTR/NoPadding</value>
</property>
<property>
<name>dfs.encrypt.data.transfer.cipher.key.bitlength</name>
<value>256</value>
</property>
Thanks

Try set dfs.block.access.token.enable to true.
