Hello Impala Public Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/21142
to look at the new patch set (#3).
Change subject: IMPALA-12737: List key columns in query history
......................................................................
IMPALA-12737: List key columns in query history
Adds "Key Columns" to the query profile, enumerating a
comma-separated list of columns that are important for estimating
cardinality of the query. Also adds "key_columns" to impala_query_log
and impala_query_live with the same content.
Relevant columns are those referenced in 'where', 'group by', and
'having' clauses of a 'select' query; and the 'where' clause of an
'update' or 'delete' statement.
Requires 'drop table sys.impala_query_log' to recreate it with the new
column.
