IMPALA-7102 (Part 1): Disable reading of erasure coding by default
In this patch we add a query option ALLOW_ERASURE_CODED_FILES, that
allows us to enable or disable the support of erasure coded files. Even
though Impala should be able to handle HDFS erasure coded files already,
this feature hasn't been tested thoroughly yet. Also, Impala lacks
metrics, observability and DDL commands related to erasure coding. This
is a query option instead of a startup flag because we want to make it
possible for advanced users to enable the feature.
We may also need a follow on patch to also disable the write path with
this flag.
Cherry-picks: not for 2.x
