--------------------------------------
Summary: XOR erasure coding unsupported by default
Key: HDDS-12146
URL: https://issues.apache.org/jira/browse/HDDS-12146
Project: Apache Ozone
Issue Type: Bug
Components: EC
Affects Versions: 1.4.1
Reporter: Frens Jan Rumph
Following [the
documentation|https://ozone.apache.org/docs/1.4.1/feature/erasurecoding.html],
I tried setting up erasure coding with {{{{}}{{XOR-2-1-1024k{}}}{}}}. However,
I got the following error when attempting to create a bucket:
{{ozone sh bucket create /volume/bucket --type EC --replication XOR-2-1-1024k}}
{{Invalid replication config EC/2-1-1024k. Config must match the pattern
defined by ozone.replication.allowed-configs
(^((STANDALONE|RATIS)/(ONE|THREE))|(EC/(3-2|6-3|10-4)-(512|1024|2048|4096)k)$)}}
I had to change {{ozone.replication.allowed-configs}} for it to work:
{{(^((STANDALONE|RATIS)/(ONE|THREE))|(EC/(2-1|3-2|6-3|10-4)-(512|1024|2048|4096)k)$)}}
(note the added {{2-1}} after {{{}EC/{}}})
Is this by design or just a simple omission in the regex in
{{{}org.apache.hadoop.hdds.client.ReplicationConfigValidator#validationPattern{}}}?
