Change subject: IMPALA-3376: Extra definition level when writing Parquet files ...................................................................... IMPALA-3376: Extra definition level when writing Parquet files Currently, when writing a new value to a parquet file, we write the definition level before checking if there's enough space on the current page for the value. If there isn't, we create a new page and rewrite the definition level to it, but this leaves the definition level for that value still written to the old page. To fix this, we should make sure that we have enough space to write both the definition level and the value before writing either. This patch also modifies the parquet-reader tool, which reads parquet files and performs minimal sanity checking on their metadata, to check for extra definition levels, and adds a test that runs the tool automatically.
