Gabor Bota commented on HADOOP-13649:
-------------------------------------
Changes totally make sense, +1 (nonbinding).
Thanks for the correction, the following mistake in my patch is astonishing:
{code:java}
expireAfterAccess(expiryAfterWrite, TimeUnit.SECONDS)
{code}
I'm still not quite there with the naming.

> LocalMetadataStore is primarily a reference implementation for testing. It
> may be useful in narrow circumstances where the workload can tolerate
> short-term lack of inter-node consistency: Being in-memory, one JVM/node's
> LocalMetadataStore will not see another node's changes to the underlying
> filesystem.
> To put a bound on the time during which this inconsistency may occur, we
> should implement time-based (a.k.a. Time To Live / TTL) expiration for
> LocalMetadataStore
