Upendra Yadav commented on HIVE-4312: ------------------------------------- Is there any plan to give this support? > Make ORC SerDe support replace columns > -------------------------------------- > > Key: HIVE-4312 > URL: https://issues.apache.org/jira/browse/HIVE-4312 > Project: Hive > Issue Type: Improvement > Components: File Formats > Affects Versions: 0.11.0 > Reporter: Kevin Wilfong > > In the alterTable method of DDLTask.java there is an explicit list of SerDes > which support the replace columns command. ORC should support this, at least > for partitioned tables, maybe not unpartitioned tables. > This may be as simple as adding it to that list, but I suspect some > significant changes will be needed to make this work the the > CombineHiveInputFormat (e.g. where are combined and one split has a column > stored as a string and in the other it is stored as an int). -- This message was sent by Atlassian JIRA (v6.4.14#64029)
