[jira] [Commented] (PARQUET-442) Convert flat SchemaElement vector to implied nested schema data structure

    [ https://issues.apache.org/jira/browse/PARQUET-442?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15129064#comment-15129064 ] 

Wes McKinney commented on PARQUET-442:
--------------------------------------

I'm getting going on this, otherwise we're going to accumulate a bunch of refactoring debt with {{ColumnReader}} and its forthcoming unit tests (ColumnReader needs to accept an as-yet-unnamed ColumnSchema parameter containing the {{parquet::SchemaElement}} and the max rep/def levels computed by analyzing the schema tree).
