Description

When we run secure datanode on IBM PowerPC with IBM JDK, the jsvc wrong with error

jsvc error: Invalid JVM name specified server

This is because of the HDFS_DATANODE_SECURE_EXTRA_OPTS "-jvm server".
For IBM JDK it is enough to run it without -jvm server.
So I think we can check if IBM jdk in hdfs-config.sh before setting HDFS_DATANODE_SECURE_EXTRA_OPTS.
