[jira] [Updated] (HDFS-9962) Erasure Coding: need a way to test
multiple EC policies
[ https://issues.apache.org/jira/browse/HDFS-9962?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Takanobu Asanuma updated HDFS-9962:
-----------------------------------
Description:
Now that we support multiple EC policies, we need a way test it to catch potential issues.
*UPDATE:*
Since many existing EC unit tests need some changes to use multiple EC policies, it would be good to create a jira for every few tests. Based on some discussion in HDFS-7866 and HDFS-9962, this task follows the below idea.
* Default policy (RS-6-3) always gets tested.
* Create a random ec policy test if the test is long-running (e.g. using minicluster many times).
* If the test is not long, all policies test with parametrizing would be better.
If you are interested in this work, please join it and create a jira under this jira.
