Known Issues

  • DRILL-8511: Experimental JSON reader (configuration option store.json.enable_v2_reader set to true) fails with IllegalStateException when a batch reaches the rows limit.
  • HTTP CSV Plugin. Enabling headerExtractionEnabled: true in csvOptions causes data loss by misinterpreting the first data row as the header. Leave this setting disabled or omitted, as header extraction is handled automatically.

Limitations

  • Some unequal left joins may start failing in this release. For details, see Unequal JOIN Support.
  • The Hive storage plugin for Drill does not support reading of the parquet timestamp type with the int64 logical type.
