-----------------------------------
Summary: 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
{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.
