> EC: Fix verifyClusterSetup output in case of an invalid param
> -------------------------------------------------------------
>
> Key: HDFS-17056
> URL: https://issues.apache.org/jira/browse/HDFS-17056
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: ec
> Reporter: Ayush Saxena
> Priority: Major
> Labels: newbie
>
> {code:java}
> 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.
