Hello Quanlong Huang, Abhishek Rawat, Yifan Zhang, Zihao Ye, Wenzhe Zhou,
Impala Public Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/21020
to look at the new patch set (#5).
Change subject: IMPALA-12801: Increase query_log_size from 100 to 200.
......................................................................
IMPALA-12801: Increase query_log_size from 100 to 200.
Coordinator's /queries page is useful to show information about recently
run and completed queries. Having more entries will be helpful to
inspect queries that completed further back. The maximum entry of this
table is controlled by 'query_log_size' flag. Higher value means more
queries to keep, but it also cost more memory overhead in coordinator.
This patch increase 'query_log_size' default value from 100 to 200. This
patch also add flag 'query_log_size_in_bytes' (default to 2GB) as an
additional safeguard to evict entry from query_log_ when this limit
exceeded, preventing query_log_ total memory to grow prohibitively
large. 'query_log_size_in_bytes' is used in combination with
'query_log_size' to limit the number of QueryStateRecord to retain in
query_log_, whichever is less.
Testing:
- Pass exhaustive tests.
