DataNode start failed for permession denied on keystore file

DataNode start failed for permession denied on keystore file

Hello to everyone,

I added two nodes to a cluster configured with ssl on HDFS, YARN and MapReduce. I successfully installed DataNode processes but DataNode start process fails for new hosts with following error on the keystore used for ssl configuration

java.io.filenotfoundexception: /etc/security/server keys/keystore.jks (permission denied)

both directories and file are owned by yarn user and hadoop group and permissions are 660: I have the same configuration on other nodes in the cluster which there is no failure in starting DataNode processes for.

Any suggestions?

Thanks in advance!
