This commit adds the plumbing created by IMPALA-13653. The Calcite
planner is now called from Impala's Frontend code via 4 hooks which
are:
- CalciteCompilerFactory: the factory class that creates
the implementations of the parser, analysis, and single node
planner hooks.
- CalciteParsedStatement: The class which holds the Calcite SqlNode
AST.
- CalciteAnalysisDriver: The class that does the validation of the
SqlNode AST
- CalciteSingleNodePlanner: The class that converts the AST to a
logical plan, optimizes it, and converts it into an Impala
PlanNode physical plan.
To run on Calcite, one needs to do two things:
1) set the USE_CALCITE_PLANNER env variable to true before starting
the cluster. This adds the jar file into the path in the
bin/setclasspath.sh file, which is not there by default at the time
of this commit.
2) set the use_calcite_planner query option to true.
This commit makes the CalciteJniFrontend class obsolete. Once the
test cases are moved out of there, that class and others can be
removed.
