This patch adds documentation for AGG_MEM_CORRELATION_FACTOR and LARGE_AGG_MEM_THRESHOLD option introduced in Apache Impala 4.4.0. IMPALA-12548 fix behavior of AGG_MEM_CORRELATION_FACTOR. Higher value will lower memory estimation, while lower value will result in higher memory estimation. The documentation in ImpalaService.thrift, however, says the opposite. This patch fix documentation in thrift file as well. Testing: - Run "make plain-html" in docs/ dir and confirm the output. - Manually check with comments in PlannerTest.testAggNodeMaxMemEstimate() Change-Id: I00956a50fb7616ca3c3ea2fd75fd11239a6bcd90 Reviewed-on: http://gerrit.cloudera.org:8080/21793 Tested-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com> Reviewed-by: Michael Smith <michael.smith@cloudera.com>
