> Amount of region cached in the region metrics not updated for a region
> immediately after it is flushed with cacheOnWrite turned on

> Key: HBASE-29035
> URL: https://issues.apache.org/jira/browse/HBASE-29035
> Project: HBase
> Issue Type: Bug
> Components: Balancer, BucketCache
> Affects Versions: 3.0.0-beta-1, 4.0.0-alpha-1, 2.7.0, 2.6.1
> Reporter: Rahul Agarkar
> Assignee: Rahul Agarkar
> Priority: Major
> Labels: pull-request-available
> Fix For: 3.0.0, 4.0.0-alpha-1, 2.7.0
>
>
> An issue has been observed where if a new region is created and flushed with
> the configuration "hbase.rs.cacheblocksonwrite" is set to true, then, the
> region metrics does not reflect the amount of region cached for this new
> region. It starts reflecting the correct metric when this region is reopened
> for whatever reason.
>
> The steps to reproduce this issue are as follows:
> * Create a table {{create 'tprefetch', 'cf'}}
> * {{{}{}}}Insert a record in the table {{put 'tprefetch', 'row1', 'cf:col1',
> 'aaaaa'}}
> * {{{}{}}}{{{}flush 'tprefetch'{}}}
> After the flush, query the region metrics for this region and it will show
> that the region is 05 cached. This leads to the cacheAwareLoadBalancer take
> incorrect decisions whenever a region server is restarted.
