Currently, many of hive DDLs are not supporting specifying database name, which
is partly fixed on https://issues.apache.org/jira/browse/HIVE-3589. I'm waiting
for the issue committed and expecting to use it for other DDLs.
ql/src/java/org/apache/hadoop/hive/ql/parse/DDLSemanticAnalyzer.java:755 I
agree but can't think of an alternative way. It's same situation for all other
DDLs.
ql/src/java/org/apache/hadoop/hive/ql/exec/DDLTask.java:3912 I admit I've
just copied it from Hive.class. Could you do that when updating patch for
HIVE-3701? I don't know well of differences among the hadoop versions.
ql/src/java/org/apache/hadoop/hive/ql/ErrorMsg.java:249 Agreed.
ql/src/java/org/apache/hadoop/hive/ql/parse/DDLSemanticAnalyzer.java:749 done.
