Íñigo Goiri commented on HDFS-12773:
------------------------------------

Internally, we use the ZooKeeper implementation from HDFS-10631.
[~xkrogen] did a deployment with the HDFS implementation and had a bunch of issues with multiple
writers.
These improvements should take of this.

> HDFS-10630 introduced a filesystem implementation of the State Store for unit tests.
However, this implementation doesn't handle multiple writers concurrently.
