Subject Hive parquet on EMR
Date Fri, 01 Apr 2016 19:09:21 GMT

We have a Hive (v 1.0.0) cluster at EMR and data stored in parquet files.
When querying data, it fails to return result, causing a NPE. We think the
error may be related with Hive deserialization, since can query data
without problems when using other technologies (ex.: Presto).

Here we provide the stacktrace of the exception we get
<>. We checked Hive Parquet support
<> and release notes
<>, and seems
map and struct types are supported for this version (1.0.0) Our Parquet
schema involves the following types: string, boolean, map, struct.

Did anyone had a similar experience? Is there a workaround for this?

Thank you in advance,
