    [ https://issues.apache.org/jira/browse/PARQUET-1160?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16580316#comment-16580316 ] 

Ted Haining commented on PARQUET-1160:
--------------------------------------

The Data Integration software from HVR ([https://www.hvr-software.com/)] produces Parquet files that have BYTE_ARRAY-backed decimals.  A small sample data file with random data produced by HVR is attached.

> These are valid in the parquet spec, but it seems like no system in use today implements a writer for this type.
> What systems support writing Decimals with this underlying type?
