Takanobu Asanuma commented on HDFS-9962:
----------------------------------------
Hello [~andrew.wang] and [~drankye],
While writing the patches for the subtasks of this jira, I thought it is better
to check all EC policy every time by parametrized test, rather than choosing an
EC policy randomly. Comparing to the random policy test (see HDFS-12547), the
parametrized test (see HDFS-12587) keeps idempotency and simple code. As a
disadvantage, the parameterized test may become more flakey (especially when
using minicluster).
I want to hear your opinions. Which do you think is better?
