Thanks to Todd's help, thanks to everyone!    When I adjusted my virtual machine memory to 4G, the install successfully and the disk doesn't occur heavily swapping again.    Summary of the installation process, when some steps of failure occurred during the installation process, in most cases, try again and wait to complete installation.  Such as the HDFS create /tmp failure , generally retry can be successful, no need to add 127.0.1.1 /etc/hosts.   Thanks again ...
