Verify the Related Query Option

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_FILES is enabled by default.
You may use the ALLOW_ERASURE_CODED_FILES query option to disable the support of erasure coded files in Impala. When the ALLOW_ERASURE_CODED_FILES query option is set to FALSE, Impala returns an error when a query requires scanning an erasure coded file. Type: BOOLEAN Default: TRUE
