----------------------------------
hi, [~till.rohrmann]
I have other questions and suggestions:
1. I want to know if will also delete invalid directories on HDFS, similar to
zk metadata? because most of the metadata of HA is stored on HDFS. such as
when job is failed.
2. when the job is canceled, the job's metadata is deleted as default , but i
think it also should delete the corresponding directory, such as
\{{jobId}}/shared and \{{jobId}}/taskowned.
> Flink HA didn't remove ZK metadata
