Summary: CLONE - Erasure Coding: Provide ECSchema validation when
setting EC policy
Key: HDFS-10152
URL: https://issues.apache.org/jira/browse/HDFS-10152
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: dragon
Assignee: J.Andreina
Fix For: HDFS-7285
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.
