Most of the problems listed in Figure 7-1 relate to missing components (such as Impala not having been
installed) or a home directory not existing for the login account on Linux. Make sure that the home directories exist
and that there is a suitable environment shell file, such as .bashrc, set up for the account. Also, as stated earlier, make
sure that the account has a home directory on HDFS under /user. Finally, make sure that the Linux user ID number of
the Linux account is greater than 500 to avoid scripting errors in Hue.
If there are no errors, you will see the Home page for Hue (Figure 7-2 ), which is divided into three sections of
functions: those for Query, Hadoop, and Workflow. The same functions are displayed with icons across the top of the
Hue screen. In Figure 7-3 , for example, the Home icon is highlighted.
