IMPALA-5842: Write page index in Parquet files
This commit builds on the previous work of
Pooja Nilangekar: https://gerrit.cloudera.org/#/c/7464/
The commit implements the write path of PARQUET-922:
"Add column indexes to parquet.thrift". As specified in the
parquet-format, Impala writes the page indexes just before
the footer. This allows much more efficient page filtering
than using the same information from the 'statistics' field
of DataPageHeader.
I updated Pooja's python tests as well.
