However, > currently Hive only recognizes decimals backed by binaries (either {{BINARY}} > or {{FIXED_LEN_BYTE_ARRAY}}). > We can improve this by providing a more general {{PrimitiveConverter}} > [here|https://github.com/apache/hive/blob/release-1.2.1/ql/src/java/org/apache/hadoop/hive/ql/io/parquet/convert/ETypeConverter.java#L127-L137]. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
