https://community.cloudera.com/t5/Support-Questions/network-scoped-alias-is-supported-SOLVED/m-p/177226#M139476 <P>Hi <A rel="user" href="https://community.cloudera.com/users/83518/s0545166.html" nodeid="83518">@De ba</A></P><P>The issue is here:</P><P>&gt;&gt;docker-deploy-hdp265.sh:30:[: hdp: unexpected operator&lt;&lt;</P><P>The posix shell that you are using does not recognize '==' for string equality and hence the 'hostname' variable is not set. This is resulting in a null string being passed to the 'network-alias' option in docker run command and hence the issue.</P><P>How are you executing the script 'docker-deploy-hdp265.sh' ?</P><P>You can try the following options as a work around and that should set the 'hostname' variable to a proper value and then docker run would execute successfully.</P><P>1. Can you try replacing '==' with '=' in the following if condition code.</P><P># start the docker container and proxy</P><P> if [ "$flavor" = "hdf" ]; then </P><P> hostname="sandbox-hdf.hortonworks.com"</P><P> elif [ "$flavor" = "hdp" ]; then </P><P> hostname="sandbox-hdp.hortonworks.com"</P><P> fi</P><P>2. Try running the script as 'bash docker-deploy-hdp265.sh'</P><P>3. Though not recommended, manually set the variable 'hostname' as follows in the script instead of the if condition.</P><P> hostname="sandbox-hdp.hortonworks.com"</P><P>Let me know how it goes.</P><P>Thanks</P><P>docker-deploy-hdp265.sh</P> Sun, 01 Jul 2018 12:12:53 GMT vpaul 2018-07-01T12:12:53Z
