[jira] [Resolved] (IMPALA-781) Impala cannot read data written by using the LazyBinaryColumnarSerDe (Hive's new default SerDe for RC file in Hive v.12)

     [ https://issues.apache.org/jira/browse/IMPALA-781?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Tim Armstrong resolved IMPALA-781.
----------------------------------
    Resolution: Won't Do

I don't think we're likely to invest effort at this point into improving RCFile support, given that Parquet is now the standard.

> Impala cannot read data written by using the LazyBinaryColumnarSerDe (Hive's new default SerDe for RC file in Hive v.12). For the short term we need to add an analysis check to say this is not supported, but we should also update our RCFile scanner to support the new format.
