Zhe Zhang commented on HDFS-8853:
---------------------------------
Thanks [~andreina] for the patch. Do you mind rebasing it?
I was also thinking about the issue when creating HDFS-8833 patch. In the long
term, it might be better for the client to pass a {{String}} to NN instead of
the actual policy/schema.
> Erasure Coding: Provide ECSchema validation when creating ECZone

> 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.
