Govind Menon commented on STORM-2171:
-------------------------------------
Spoke to [~revans2].
* Will be removing redundant ZK state updates when using LocalFsBlobStore
* Will not connect to self when the only nimbus that has the replica is self
> blob recovery on a single host results in deadlock

> Key: STORM-2171
> URL: https://issues.apache.org/jira/browse/STORM-2171
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-core
> Affects Versions: 2.0.0
> Reporter: Robert Joseph Evans
> Assignee: Govind Menon
> Priority: Major
>
> It might be more versions but I have only tested this on 2.x.
> Essentially when trying to find replicas to copy blobs from LocalFSBlobStore
> does not exclude itself. This results in a deadlock where it is holding a
> lock trying to download the blob, and at the same time has done a request
> back to itself trying to download the blob, but it will never finish because
> it is blocked on the same lock.
