hadoop - Error: E0902: Exception occured: [User: Root is not allowed to impersonate root -


I'm trying to follow the steps Note: I am not using Cludera Distibusn of Hup

Similar to the above link, but with more descriptive I think, however, I'm getting an exception by running the command as a root user. /bin/oozie-setup.sh sharelib create -fs

Note: I have two surviving node shown in Dfshealth.jsp and I Core for three (including namenode) with assets such as the following Site.xml has been updated 

  & lt; Property & gt; & Lt; Name & gt; Hadoop.proxyuser.root.hosts & lt; / Name & gt; & Lt; Price & gt; * & Lt; / Pricing & gt; & Lt; / Property & gt; & Lt; Property & gt; & Lt; Name & gt; Hadoop.proxyuser.root.groups & lt; / Name & gt; & Lt; Price & gt; * & Lt; / Pricing & gt; & Lt; / Property & gt;

I think this is the point where I'm wrong someone could please let me guide

Note: I have followed this link like this well, but I am not able to solve my problem

I get exceptions such as unauthorized connection to the super user: Halop

Restart your hood after adding property files to core- site.xml and try, though it does not work in nominated format and it will work if it starts.

Python Equivalent for matlab cart2pol and pol2cart -

I would like to use pol2cart and cart2pol for two functions in MATLAB. Is there an equivalent Python Function? Or if we can define work? For example, I tried to use the CeMatePactor function, but it only accepts one argument, I have 2 arguments to cross the polar and REC function. P> I have tried to use this function for cart2pol: def cart2pol (x, y): theta = atan2 (y, x) rho = Sqrt (x ** 2 + y ** 2) returns (theta, ro) thanks
