Allen Wittenauer commented on HDFS-11167:
-----------------------------------------
We should be avoiding putting specific JVM fixes in the shell code like this.
It won't scale. Instead, hadoop-env.sh should specifically mention that the
secure vars should be set to null on IBM JVMs.
> IBM java can not start secure datanode with HDFS_DATANODE_SECURE_EXTRA_OPTS
> "-jvm server"

> When we run secure datanode on IBM PowerPC with IBM JDK, the jsvc wrong with
> error
> {noformat}
> jsvc error: Invalid JVM name specified server
> {noformat}
> 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.
