Tianyi Wang	61e6a47776	IMPALA-7236: Fix the parsing of ALLOW_ERASURE_CODED_FILES ... This patch adds a missing "break" statement in a switch statement changed by IMPALA-7102. Also fixes an non-deterministic test case.

Taras Bobrovytsky	8060f4d50e	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 Change-Id: Icd3b1754541262467a6e67068b0b447882a40fb3 Reviewed-on: http://gerrit.cloudera.org:8080/10646 Reviewed-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com> Tested-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com>	2018-06-29 23:26:35 +00:00
