Hmmm...I'm having trouble accessing the parent, 
https://gerrit.cloudera.org/#/c/25001/

Can you resubmit that one?

http://gerrit.cloudera.org:8080/#/c/25002/1/java/calcite-planner/src/main/java/org/apache/impala/calcite/schema/ImpalaRelMdRowCount.java
File 
java/calcite-planner/src/main/java/org/apache/impala/calcite/schema/ImpalaRelMdRowCount.java:

http://gerrit.cloudera.org:8080/#/c/25002/1/java/calcite-planner/src/main/java/org/apache/impala/calcite/schema/ImpalaRelMdRowCount.java@75
PS1, Line 75:     RelNode scanInput = RelUtil.unwrapRelNode(input);
Can we put all (or most) of this new code in a separate method. I think it's 
easier to read if the top level "getRowCount" method stays small-ish and 
contains mostly top level-ish operations.
