Subject [jira] [Updated] (HIVE-14146) Column comments with "\n" character "corrupts" table metadata
Date Thu, 04 Aug 2016 08:44:20 GMT

     [ https://issues.apache.org/jira/browse/HIVE-14146?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Peter Vary updated HIVE-14146:
------------------------------
    Attachment: HIVE-14146.10.patch

Several more testcase changes:
- create_with_constraints.q.out - printing column names in constrains was not indented correctly
before - my patch incidentally solves this
- alter_table_invalidate_column_stats.q.out, columnstats_part_coltype.q.out - column headers
was not indented appropriately
- alter_view_as_select_with_partition.q - forget to add to the patch last time -multiline
select is indented

The other testcases were about printing null instead of empty string. The patch updated to
print it correctly.
