[jira] [Updated] (DRILL-7825) Error: SYSTEM ERROR:
RuntimeException: Unknown logical type
[ https://issues.apache.org/jira/browse/DRILL-7825?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
ian updated DRILL-7825:
-----------------------
Description:
Parquet logical type UUID fails on read. Only workaround is to store as text, a 225% penalty.
Here is the schema dump for the attached test parquet file. I can read the file okay from R and natively through C++.
3961 $ parquet-dump-schema uuid.parquet
required group field_id=0 schema
{ required fixed_len_byte_array(16) field_id=1 uuid_req1 (UUID); optional fixed_len_byte_array(16) field_id=2 uuid_opt1 (UUID); required fixed_len_byte_array(16) field_id=3 uuid_req2 (UUID); }
I'm new.. I put this as MAJOR from reading the severity definitions, but gladly defer to those who know better how to classify.
