We have a table created in the hive as parquet format, and data ingested into
it through Hive command.
The hive version is 0.12.0, and parquet version is 1.3.2.
When querying this table in the Hive, the mapper failed with the following
error, is this due to the NULL value in the data?
Do we have any jira related to this? Or what version I can expect this bug
fixed in Parquet?
I google around, and found out the exactly the same issue discussed here:
https://groups.google.com/forum/#!topic/parquet-dev/cxcz2QG7ScY
But no result about if it is fixed in the future version.
Thanks
Yong
