Zoltan Haindrich commented on HIVE-19171:
-----------------------------------------
[~alangates] runtime statistics are collected if the query fails (for example:
map join problems; oom); the query is currently re-execute using the runtime
stats
by persisting this data in the metastore makes the "re-execution" happen only
once...the statistics are saved in the metastore; and it will probably just
work for the end user
Its not ready yet...but my wip branch is at
https://github.com/apache/hive/compare/master...kgyrtkirk:HIVE-19171-persist-metastore
if you would like to take a look;
it will make the following changes at the metastore side:
* a new metastore table
* 2 new thrift calls
> Persist runtime statistics in metastore
