Agree with @ayushtkn , the current works as designed, if don't specify any
policy the result is if validate all the enabled policies.

> bin/hdfs ec -verifyClusterSetup XOR-2-1-1024k
> 9 DataNodes are required for the erasure coding policies: RS-6-3-1024k,
> XOR-2-1-1024k. The number of DataNodes is only 3. {code}
> verifyClusterSetup requires -policy then the name of policies, else it
> defaults to all enabled policies.
> In case there are additional invalid options it silently ignores them, unlike
> other EC commands which throws out Too Many Argument exception.
