[jira] [Updated] (HIVE-8808) HiveInputFormat caching cannot work
with all input formats
[ https://issues.apache.org/jira/browse/HIVE-8808?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Brock Noland updated HIVE-8808:
-------------------------------
Description: 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. (was: In {{HiveInputFormat}} we implement instance caching (see {{getInputFormatFromCache}}). This assumes that inputformats are stateless but I don't think this assumption is true, especially with regards to HBase.)
