Nick Dimiduk commented on HIVE-8808: ------------------------------------ Yes, it looks like our input formats are stateful. We're set up to specify a config object and that's closed over to provide custom record readers, based on which mapred API is being implemented. > HiveInputFormat caching cannot work with all input formats > ---------------------------------------------------------- > > Key: HIVE-8808 > URL: https://issues.apache.org/jira/browse/HIVE-8808 > Project: Hive > Issue Type: Bug > Reporter: Brock Noland > > In {{HiveInputFormat}} we implement instance caching (see > {{getInputFormatFromCache}}). In HS2, this assumes that InputFormats are > stateless but I don't think this assumption is true, especially with regards > to HBase. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
