We are using MCR inside java web application .Its working fine , but in some certain cases MCR crashes. In server log we found below mentioned message,
*Matlab M-code Stack Trace ...
com.mathworks.toolbox.javabuilder.MWException: An error occurred while initializing the component.
Could not access the MCR component cache.

you should set yarn.nodemanager.user-home-dir as a valid directory
for example
property name>yarn.nodemanager.user-home-dir</name value/home/hadoop</value> /property
which can be set in yarn-site.xml

Yes, in my case of using Hadoop and Spark, yarn.nodemanager.user-home-dir should be set in the yarn-site.xml, otherwise I get "Could not access the MATLAB Runtime component cache" error.
