------------------------------------------
[~stiga-huang] Is this a user-facing query option that should be documented?

> Key: IMPALA-8913
> URL: https://issues.apache.org/jira/browse/IMPALA-8913
> Project: IMPALA
> Issue Type: New Feature
> Reporter: Quanlong Huang
> Assignee: Quanlong Huang
> Priority: Major
> Fix For: Impala 3.4.0
>
>
> IMPALA-8058 added a flag, disable_hbase_row_est, in the QueryCtx for tests to
> bypass the codes of estimating HBase row stats from HBase RPCs and fall back
> to HMS row count stats.
> It's useful for point queries on high loaded HBase clusters, where we should
> reduce the #RPCs to HBase.
