Hello Vuk Ercegovac,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/9139
to look at the new patch set (#5).
Change subject: IMPALA-6228: Control stats extrapolation via tbl prop.
......................................................................
IMPALA-6228: Control stats extrapolation via tbl prop.
Introduces a new TBLPROPERTY for controlling stats
extrapolation on a per-table basis:
impala.enable.stats.extrapolation=true/false
The property key was chosen to be consistent with
the impalad startup flag --enable_stats_extrapolation
and to indicate that the property was set and is used
by Impala.
Behavior:
- If the property is not set, then the extrapolation
behavior is determined by the impalad startup flag.
- If the property is set, it overrides the impalad
startup flag, i.e., extrapolation can be explicitly
enabled or disabled regardless of the startup flag.
Testing:
- added new unit tests
- code/hdfs run passed
