---------------------------------------
Summary: Revise basic stat states for estimations
Key: HIVE-18062
URL: https://issues.apache.org/jira/browse/HIVE-18062
Project: Hive
Issue Type: Sub-task
Components: Statistics
Reporter: Zoltan Haindrich
basic stat states might be misleading; because currently estimations also get
the *COMPLETE* qualifier in most cases..
proposed definitions for the states:
* {{NONE}}
** on table: no information (afaik currently this can't happen)
** estimation tree: all nodes in the estimation tree were NONE
* {{PARTIAL}}:
** on table: the current information is estimated from data size
** estimation tree: contains at least one NONE/PARTIAL; and at least 1
PARTIAL
* {{COMPLETE}}:
** current information is correct (calculated by statstask-s)
** estimation tree: the whole subtree has COMPLETE status
document/change states to comply with the above definitions.
