> ScanResponses contain only one cell each
> ----------------------------------------
>
> Key: HBASE-21032
> URL: https://issues.apache.org/jira/browse/HBASE-21032
> Project: HBase
> Issue Type: Bug
> Components: Performance, Scanners
> Affects Versions: 2.1.0
> Environment: HBase 2.1.0
> Hadoop 2.8.4
> Java 8
> Reporter: Andrey Elenskiy
> Assignee: Andrey Elenskiy
> Priority: Major
> Fix For: 3.0.0, 2.2.0, 2.1.1
>
> Attachments: App.java, HBASE-21032-v1.patch, HBASE-21032-v1.patch,
> HBASE-21032.patch
>
>
> I have a long row with a bunch of columns that I'm scanning with
> setAllowPartialResults(true). In the response I'm getting the first partial
> ScanResponse being around 2MB with multiple cells while all of the consequent
> ones being 1 cell per ScanResponse. After digging more, I found that each of
> those single cell ScanResponse partials are preceded by a heartbeat (zero
> cells). This results in two requests per cell to a regionserver.
> I've attached code to reproduce it on hbase version 2.1.0 (it works as
> expected on 2.0.0 and 2.0.1).
> [^App.java]
> I'm fairly certain it's a serverside issue as
> [gohbase|https://github.com/tsuna/gohbase] client is having the same issue. I
> have not tried to reproduce this with multi-row scan.
