Impala already supports the basic functionalities of erasure-coding. Before this release, EC was turned off by default because Impala lacked metrics, observability and DDL commands related to erasure coding.
For this release, the query option
ALLOW_ERASURE_CODED_FILESis enabled by default.
You may use the
ALLOW_ERASURE_CODED_FILESquery option to disable the support of erasure coded files in Impala. When the
ALLOW_ERASURE_CODED_FILESquery option is set to FALSE, Impala returns an error when a query requires scanning an erasure coded file. Type: BOOLEAN Default: TRUE
