> Presently the {{DFS#createErasureCodingZone(path, ecSchema, cellSize)}} doesn't have
any validation that the given {{ecSchema}} is available in {{ErasureCodingSchemaManager#activeSchemas}}
list. Now, if it doesn't exists then will create the ECZone with {{null}} schema. IMHO we
could improve this by doing necessary basic sanity checks.
